Engine Error "invalid reference in get_standable_point"

System: Win7 home premium
12 GB RAM
Intel Core i7 @ 2.4GHz
Nvidia GT650M

The only activity I had going on in game was wood gathering, no building mining or combat. Not sure if this relates to wood gathering or the large cat that laid on my keyboard a couple of seconds before this popped up. No change in performance or noticable glitches in game

Seen this in current build. Happened right after I killed some wolves and some others ran away.
