Hyena boss in map "Wetlands bugged

I'm to simple minded to understand how I share the pictures.. I've had this problem twice now on "Wetlands" with the hyena boss from Savannah map and first boss of act 2. All the small hyenas just walks around and the boss just regens. Can't do anything. I went offline for 15min to get sent out. I didn't even do the same node but the next time I got a Wetlands node the same thing happend... I'm playing ED/contagion on a lich. I'm wondering it there's something about my curses on the boss. This time I tried to just walk in without hitting anything but the same problem happend. Lost two corrupted nexuses now to this, hard to progress when all nexuses seem to be wetlands..

Also just had this same bug in maps

I'm having the same issue, first time the small hyenas kept spawning in without being hostile. Second time they stopped spawning but the boss is still bugged.
