ToME: the Tales of Maj'Eyal

Not a huge deal, but it appears that there is a bug that prevents adventurers who gain tinkers (at least via escort) after taking the demon seed talent from being able to apply tinkers to their non-demon seed slots as no new slots are added to those items to apply. This was noted on a save with no addons other than the official Ashes/Embers/Cults/Possesor/Item Vault on Steam.

The slots still "exist" and you can drag&drop tinkers onto the items, but you can't use the context menu to "attach" to an item.
