ToME: the Tales of Maj'Eyal

I have a fair amount of mods...but don't think any of them are in the mix here? At least the callstack doesn't look that way. Not in a convenient place to test. Lemme know if it does seem like it's mods and I may try and figure which one.

Mentions minimalist, but I don't have a mod on by that name? Think that's just one of the UIs.

Is primal infusion working for others?

Starting a new char in dev mode. Giving them one, doesn't seem to crash.

Guessing it's vault-badness, been some time since seeing that.
