Hello, my game is modded, and for some reasons all biters and spitters of every size and every modded subspecies are able to walk trough stone walls as if they were not there. Walls will still collision with spitter projectiles if they try to shoot while phasing trough walls, but otherwise every single ennemy type and subtype of my modded game will outright walk trough walls as if they were no walls at all, there is strickly zero colision for the bugs, they don't even pathfind around.
I feel I should mention I'm playing on a belt world, and that the bugs are walking trough surfaces of water also, either shallow or deep. I am absolutely clueless and none of the ressources I could look up seem to mention this before. Please help!
