Now I know that the campaign mode is still not finished, or that this issue might have already been fixed, I think this was happening even in build 25.

when playing a 2vs2 player game the program crashes when a team (2 people) attack a site owned by the other team together
(maybe because there is only one brain actor from the defending team in battle?)
if everyone attacks unclaimed site at once there doesnt seem to be a problem
it also doesnt seem to matter if the defenders put a build budget on the site or not

here is a save file if it's needed

this is more of a problem when making missions, but the AI seems to go around the whole map through an open route
if there is even one door blocking the entrance next to the actor, or one more door than there would be on the other route

also, would it be possible to make it impossible to reveal the unseen layer through closed doors?

Can't wait for the finished campaign, we already had a blast playing it with four people through a projector!
The tech research and restrictions are gonna be really great.
