each time i get a new mod, i am having to pull up 25% of convaers in all maps, thanks to things on them changing to other things and backing up all buildings, as the things can never be used by them.
and now the game is restarting level by itself. hours of work gone.
why is that going on?

is there a possible bug with one of your mods? that may be the case.
although im not the best at knowin since the only time ive had to deal with something like that was when i was booting the game up, and even then it was due to 2 many mods.
restarting the game may work, along with verifying files, but idk.
