It looks like players and AI characters are bugging out around fires, they start woobeling up and down until you get some 5-10 meters away from it. Happens around cars on fire and on lite fireplaces.

Just replicated this myself. I placed a fireplace and then circled it with units. Placed some units further away and then lit it with a script. All but one unit within 29 meters began to change back and forth between two animations. The one unit that did not was 28 meters away. Was able to repeat by switching the fire off and on again. Player and AI are both affected.
