Added water to the map tags, removed herobrine

Fixed Lua Error that would appear when loading a save, crane magnet still drops though, but that happens with all maps with cranes. Also tweaked the helicopter pathing so they should get stuck less.

Accidental Update

Removed the .ain file (the info_node movement file) so that people can edit the ai nodes in the map (the one which came with this originally would overwrite any which were made/edited manually afterwards). The Navmesh is unaffected, and can still be found here : https://steamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2322433200

Initial addon creation.
