Is this a bug, or something legit but annoying?
It's SR's Symbol of Weakness, I've made all others disease effects not permanent at player's request but this one seems to still be permanent. In theory I don't like disease effects to go away on their own but I suppose I'll have to make this too go away with a rest.
A bit late, but I like having to cure diseases by casting cure disease spell or visiting a temple (and not by resting). Though temples don't have cure disease as their list of services, just restoration spells, which are pricey for not being level drained. I don't see what the big deal is. It really becomes a non-issue at higher levels when priest gain more spell lots.
