This all started with a mount, but I don't know if it is technically a mount bug. I rent a mount and it is normally fine. It wears off and I rent another mount. At this point so far every single time the mount on the second renting will never fly. So I exit out of the game(I don't log out, I use exit) I log back in and all my skills, quest etc are gone. I open my abilities book and it is 0/0. I log out seriously 20+ times and it is still like this. I don't know what makes it come back, but eventually, so far I log back in and my skills are back. I didn't think about reporting it evem though it has happened more than once, but this last time I am still logging in and out trying to get my skills back. I put the severity at severe since well, you lose everything, so that is pretty severe imo lol.
