Hey there,
encountered a annoying "bug" today in Arx. I have seen some postings already about it on the steam community. Want to make it a little bit more "public".
There can be an infinite respawn of Cursed Revenants in the Lizard Consulate. Everything is full of Necrofire and I know I can remove those with Blessing and so on, but... some Necrofires are inside the walls and that results in constant respawn.
Solved my problem after discovering those, finally.. after 2 hours of fighting and loading savegames.
My solution was to place one of my characters ON the respawn point near the wall (where the necrofire was). Solved it for me, but I hope there could be some hotfix for my second run.
