Skimping on details since others have posted similar.
Got a crash "Exception has been thrown by the target of invocation".
Happened in... er... normal difficulty snowy place
after mouseovering(or trying to click?) a Gorgon I summoned with WONAFYT. Was a level 3 Human Tinker worshipping the Nature deity.
Edit:
2nd crash when mouseovering a summoned goblin, Eastern Tundra again, same deity, class, race, level. Not touching WONAFYT for time being
3rd crash on guitar use, same error.
