Escort in old forest, portal somewhere southeast of escort. The only path goes quite a ways straight north before turning east, but escort doesn't follow at all. I dig an intersection into the n-s path about 10 steps above escort, but she still doesn't follow. I figure maybe she will follow when i move towards the portal (assuming maybe a max distance was set somewhere) with a backup plan of returning and digging a straight path after i found the portal, but apparently when you get out of range the escort fails (again, an assumption), because at some point the quest HAD failed and I don't think there were monsters to kill her.
So i suppose path finding may need a bit of an improvement

Case 2:
Portal on final old forest level. When i encounter the boss, my escort turns hostile.
I'm pretty sure i did not fire my sun burst to cause that.
P.S. Apropos allies turning hostile, that happened to me when i used sun burst with the kidnapped merchant in the area of effect. IMO allies should be a bit more tolerant towards friendly fire, i would have healed him afterwards anyway
