Edited old: z_resolve_zombie_collision_multiplier "0.15", z_resolve_zombie_collision_auto_multiplier "0" The problems: Commons got stuck/freezed in stack (like they're glued/tied together) when they spawned at a spawn point. Very frequently happened. Commons randomly just disappeared out of thin air, when they fell down or just when they're running towards you. Very frequently happened. Commons got spawned in your face sometimes. I guess this one is v1.10, idk. I'm really afraid to test this out yet. In the meantime, I'll use the old version v1.8 although commons have stuttering problem when climbing obstacles in that one.

I see your concerns but the problems you described mostly likely were fixed in the latest update.
1.9 version used the wrong sum variable for commons collision which could cause all of the problems you described and it also explains why using the old settings didn't fix it
