I think prepatcher works fine but beyond 450 mods I just have no chance of avoiding compatibility problems, and prepatcher being that early in the list simply make me unable to play, the rimworld ui doesnt display at all.

I leave it here in case someone has the same situation but paradoxally avoid using too many optimization mods because there is always a high risk of errors and these makes the game unplayable.

@atlus I think I figured it out, it is incompatible with most roofing mods (works with some skylights though) I spent over an hour trying to correct everything and forgot to grab a copy of the log so sadly no I don't have a copy of the crash log.

I just tried running with updated Biomes! mods and it works no problem. Show the log if you arent running already beyond broken modlist.

It seems to be a conflict specifically with Biomes! I am unsure how, or why that would be the case but the two seem to work okay without the presence of the other.

@Atlas are you able to provide log of that? Check old modpage for instructions

Yeah this was causing my game to be unable to load the main menu UI.

This break for anyone else? Had to disable it then my game worked just fine.

black menu screen would leave a log one could use to figure out the actual cause
as it cant be prepatcher when prepatcher is inactive
it usually means something prevented full startup or errored the menu gui

That being said, could be that for whatever reason some mod just broke with regards to harmony and prepatcher by extension, which is weird as my modlist was working just perfectly fine the day prior to all of that.

Also, since Prepatcher is a version of Harmony, that would mean it might also be a problem with Harmony as well. That and it would take a while to filter through every single last mod to guess whichever one might be having an issue.

I even went to the workshop folder for Prepatcher to delete it but it seems it didn't work.

Figured to try and reinstall Rimworld, only now I got to wait till the workshop has all the mods confirmed installed and such and attempt it again

No, I mean I have Prepatcher subbed to, then I noticed it having an issue when enabled, figured unsubing and resubing would fix it. Only it didn't.

@Tyrant at the time prepatcher runs the wrong assembly would already be loaded
while technically possible implementing that would be rather high effort compared to... just unsubscribing to the old mod
@Bearzapt34 prepatcher doesnt cause such issue
@Ranger Dimitri if it happens without prepatcher loaded then i dont know why you are here

Also even without having Prepatcher enabled I get that issue Tubros is having.

@Tyrant, is this specifically is causing the prepatcher to cause other patch mods not to work? Is there a fix on our end? Which is why im here

Sadly I am dealing with the bug that tubros is dealing with.

Allow mods to define a <prepatcherId>rename.to.this.pkgid</prepatcherId> element within About.xml, which, during the prepatching procedure, renames the packageId of the mod to the given value.
Because RimWorld loads things based off packageId, subscribing to more than one item with the same packageId becomes problematic. Forks would be able to have a different packageId while remaining compatible with mods that target the original packageId.

@jikulopo
So when I quit my efforts last time it didn't start. Now I just clicked the game and it started without issue.

I spend time repeating the exact same thing in the weekend and could not get it to work, now it seem fine. I am very confused but I think the error must been on my side somehow.

So the good parts is my game is running and your mod is working. The bad part is that I overwrote the bad start player.log and oldplayer.log with logs from working starts.

So I thank you for your support effort and get back to you if I manage to replicate the problem. I am rather curious about this.

@tubros grab player.log -> upload log to some paste site(eg. pastebin) -> post the link here(make sure you make that link public so i can actually read it)

This mod stopped loading with a blank main menu just stuck with picture background.

1.6: Same issue with this mod from steam, this mod from the GIT and the old 1.5 version.
Tested with only this mod and nothing else. Also tested with prepatcher, Harmony, performencefish1.5 and fishery1.5

All produce the result above

1.5: Same issue with this mod from steam, this mod from the GIT. Tested with only this mod and nothing else. Also tested with prepatcher, Harmony, performencefish1.5 and fishery1.5 and it fail to load game.

Running the orignial mod with 1.5 works fine.

Dont use that
It literally says its for learning only
Just do not use performance fish till bradson updates it

@tubros Try updating Performance Fish to the 1.6 branch version and see if that works. (This translation was provided by AI.)

@Wolves Hero I have same issue, did you find a solution?
(considering going back to RW 1.5)

@Wolves Hero If you're using RimSort check if it placed Prepatcher after Harmony, i had a very similar error and found out RimSort's autosort was putting Prepatcher after it, and it caused that same error you had

thats not how the mod manager reads that generally
it reads the tag in the about file
you can see this with a number of mods not even having versioned files
the 1.6 assembly is in the root file section
which rimworld is fully setup to read

FYI you forgot to add a 1.6 file for the mod so the mod manger says it is not compatiable for 1.6

This mod stopped loading & show 6 errors can't get main menu just stuck picture background. I unsubscribed then loading into main menu done

The issue was with the pawns in the caravan. It seemed like all of them were trying to do something and causing errors, if I remember right(at work currently) it was related to them talking to each other. Maybe teaching or something...?

@Lemniscate_Mike that log doesnt have any errors related to caravan, however there are some errors from i think conflict between VE starjack and death rattle although those dont seems to be breaking much from what i can tell

I'm getting a bunch of errors when a caravan is on the map. I'm not 100% sure if this is the cause, but didn't notice it happening before installing this.

Here's my full log!

@DumPotato read the troubleshooting section on original mods description

its causing my game to be unplayable and cant do anything

prepatcher error: Fatal error while reloading: System.Reflection.ReflectionTypeLoadException: Exception of type 'System.Reflection.ReflectionTypeLoadException' was thrown

@juniper That can be fixed with the game's file verifier. Go to options and run the option in the gear. Go to the properties of RimWorld in the installed files option. There you will see the option to verify the integrity of the files, and it will do its magic by itself.

@Juniper gonna need a log

This mod consistently causes my game to crash with a black screen at startup.

@girk It is mainly for modders to use for their mods, its very useful for performance mods specifically. Also allows you to change mod load order before game load, though using Rimsort is preferable.

whats the benefit of this mod? care to explain fellas?

it shouldnt
its steam page refers to this one

has anyone got this to work with Multi Floors? It says that zetrith.prepatcher is required.

Fish is absolutely being updated by its real modder
That forker doesnt show as reliable by their comments on the rw discords
So just wait for bradson

there is also a fork of fishery working on 1.6 on github

oh no

WITCH????????????????

it wont

Oh how I hope fishery get updated in the future...

no one knows
zetriths unseen for a year

ah so the original is legit abandoned? sad

thats just a name change in the about file
