A couple times now I have noticed bugs just chilling out together when they're clearly supposed to be fighting. A stinkbug and an orb weaver just chilling. A group of soldier ants and a spider just hanging out outside an anthill. Each of these times, once I triggered one of the enemies by getting to close or attacking one, they would then start fighting each other.
Since I can't start my game without the login crashing, I'm posting this VERY SERIOUS BUG here. Namely, I have my house raised on scaffolds, and it turns out ants and gnats can fly UNDER my house and steal from the chest THROUGH THE FLOOR. Obviously this should not happen. Love the game otherwise. Update: Having looked at my base closely, it appears that the model for the chest can easily clip through the grass floors and be opened from the outside. Not good.
