I now opened the shop officially for enchanted stuff (same for deposits). However there seem to be some rare bugs with damaged goods so I decided to block those from the shop for now. But I think this is not such a big loss. Specially if we can enable enchantments instead. Please be aware that sometimes you might get a message that an item is damaged while it should not be. That is the bug that I am talking about.
If you have an item that is new or does not show a damage-bar but is rejected from the shop system, please do not use it, keep it and tell me about it. I need to investigate to find a solution to the issue.
