In level 4 of Old Foret, I had the 'gigantic castle' (or whatever is its name) vault, and Wrathroot was neither in or out of the fort...
And of course, the zone was not marked as cleared in the quest log...

No. No crash, nor any kind of problem.
I though the problem was similar to the escort problem that can not be allocated from time to time, but that are generated on the second entrance. But reentering the level did not spawn Wrathroot.
