So now due to a bug I won't be able to recruit Regill. Nothing in the area where you're supposed to meet him loads. Party is standing in total darkness and cannot move anywhere, since there is no ground to click on.
I forget whether this setting has a purgatory, but if it does it seems that you have discovered it.
The best part was that the enemies still spawned and since they were "clickable" the party could fight them. After the battle their bodies were floating next to the party in the nothingness that was this area.
Funny enough I've managed to find the exit point! It was just difficult to spot, because it didn't show on the map; had to scroll all way through the darkness to find the little door icon.
