Creatures not avoiding lava correctly

updated to 2.0.1 on the 23/06/18 and noticed it primarily on HOG level 2 "Roads" or "Rhodes" anyway the one with the empire pathway and your claiming shrines to find the summoning stone.

Mostly, my imps don't seem to do as good a job avoiding lava as they did prior to the recent patch.

Intelligent minions and ground-based beasts seem to do the same as well.

I noticed that i would have say 20 imps and then after about 5-10 mins i'd be on creatures tab and my imp count was down to about 4.

Will try and post
