This is a mod I developed in 2020, featuring numerous bug fixes and improvements to the survivor AI’s behavior. One significant improvement is that the AI now waits for acid spit to dissolve before proceeding if it’s in its path and no alternative route is available. Previously, the AI would persistently attempt to move through the acid, only to walk away and try again.
