I'm also getting the same bug with the Game of Ur competition. It is strange because it had worked before for me but had recently stopped working.

I have the same problem, once the window to begin the ''Game of Ur Annual expo'' pops up I cant clic anywhere and I have to restart the game. It did it twice in a row.

Just got this, even though had it working earlier in the week. It seems to be pawn specific. By which I mean some combination of pawn traits/skills are just flat incompatible with the calculations used by the events. Almost be better if it had a check to automatically fail (or just give a neutral outcome) if it can't figure out what to do with the attendee.

I experienced the same bug.
I arrive at the expo location and try to click on it, but can't click on anything.
I had to force quit the game and restart it because it would not accept any operations.
The first year of the game was uneventful, and today, in the second year of the game, it occurred.

Oh good so its not just me I'm having this bug now I guess I'll just cancel the caravan

let's goooo, same here. im glad i may not be the problem here.

Also having this issue. Going to annual science expo and got the notification while in colony view - straight to world map with the popup and couldn't click it. Had to alt-f4 - But I noticed colony icons not world map icons were present.

lol yup

faced same problem when visiting annual expo. cant visit expo anymore :(

Just got this issue with the science expo. It was working before this, can't tell how recently,but recent mod additions for me that impact caravans are Map Reroll, RimQuest, and Settlement Inventory. Not sure if incompatibility or totally unrelated.
