Yeah. The only reason I stumbled over it at all was that I'd prepped Earthmother for Cursed Oasis and accidentally kicking myself out of the cursed world was already a reoccuring problem in that run, so this was just adding insult to previously self-induced injury. IMAWALing the existing plants was curse-neutral, although oddly enough I recall on another occasion de-cursing by IMAWAling no-exp revenants in the Hex Ruins, so who even knows.
... so, uh, bug reports. What's the deal with those homing piety SFX that just spin circles around you before vanishing in a puff of logic, am I right? You paladins know what I'm talking about!
