Would not work for Alexandre since that item can also be purchased. For beast man Fate quest returns, since you can also get them outside of the quest, you'd be stuck with unremovable items if you had no interest to the quests, if they were key items. At that point they should only be received while the quest is active which is not change at least I desire.
I do agree the beast tribe currency tokens should be recorded as currency. Same for Rowena tokens. For them both, there's starting to be so ridiculous amount of variety in them that having to stash each with our limited retainer space is becoming a chore. One currency tab for beast tribes, and one tab for Rowena please.
