Bug description: I was upgrading my keystone with my guild....we managed to make a level 13 keystone and upgrade it to level 14...we finished it today at 16:06 i'd assume and then I just logged on another character because the guild was making a raid and I had already made the raid on the char with keystone...btw I disconnected at the end of the dungeon...after 2 hours of raiding I came back on my main and I wanted to upgrade the key hoping that I will manage to get the appearance from completing a m15 keystone...What am I supposed to do now? I can take my other keystone from the weekly chest and hope I get nice affixes and try with that...but isnt there any way to recover my key? I didnt actually ss the key itself because I didnt think that it could dissapear...but for some reasons I ssed at the end of the m13... Btw if there's any way to get the key back it was Black Rook Hold with Teeming Overflowing and Tyrannical. I also checked the mailbox hoping its there but still nothing...
