[Oxyd] [0.18.36] Biter attack groups stuck because of stuck spitters

[triggerman602]

Many attack groups around my factory are stuck because they are waiting for stragglers that are stuck on trees. Firing artillery at the stragglers often releases the group to attack.

Save attached.

This seems to be caused by the Walls Block Spitters mod, which somehow makes it impossible for spitters to damage the trees. So I'm going to call this a bug in the mod, not in the game.
