Repeatedly over about 8 hours of play, my warrior kept losing out of combat health regen unless my character died. Then it’d work for a tiny bit til breaking again.
What’s interesting is when regen would stop (as in literally being 0 and not regening anyting) all food and even water would be instant heal to full items out of combat. I can only surmise something weird like the regen happening but not applying and instead queuing up. Then you eat something and all queued regen is applied all at once instantly.
any time regen bug was not active, food also worked as intended.
