Basically they will keep attempting to bypass the other to no avail for sometimes well over 10 seconds or until manually stopped.
I suggest possibly making a routine pathing program/code to happen when this occurs to avoid it. Basically have both vills agree to go around eachother properly.
Example at the 1:50 mark
People have recommended that another option could be when they bump they randomly choose another direction to go. As opposed to this retarded line dancing…
While others still say it is another layer of the skill of the game :microing vills… Which is super dumb.
If two vills bump each other they have to turn right every time to avoid more bumps, it should be an easy way to fix this (dunno)
