This is actually the same issue as #409

[Mutim]

So. Neither of these are resolved. I'm having the same issue. The feed says, resolved on 409, then 409 says resolved on 410...it's not. Please, can I have a fix to this? i can't turn in quest items, therefore rendering this plugin useless. Please help. thank you.
