ToME: the Tales of Maj'Eyal

This is from my cursed character in nightmare. I get a lua error where I can't continue, after I defeat the two wizards, when it's trying to suicide me.

Lua Error: /mod/addons/ashes-urhrok/superload/mod/class/Player.lua:24: attempt to call upvalue 'die' (a nil value)

Hmm. This is a remarkably similar error, albeit it under entirely different circumstances, that someone was dealing with the other day.

What addons do you have active?

Absolute most basic addons, just what came with the game basically. My addon directory is:

ashes-urhrok
tome-addon-dev
tome-items-vault

I used to have "tome-stone-wardens" in there, but I would occasionally get an error message related to stone-wardens addon when loading a save, so I removed it before creating a new character thereafter. I figured I'd just put that file back in if I ever wanted to play that class. I'm relatively newly a donator, via buying the expansion.

Looks like we can say it is the Ashes DLC then.

I don't suppose there's any way that this can be worked around so I can get the win and continue onward to kill the golem? This would have been my first nightmare win.
