This needs to be fixed in the next patch. Seriously. People is losing over 10m+ exp when LRing, there are threads with people losing all of their exp and nothing is done about it. I'M AFRAID TO LR RIGHT NOW AND WITH ME MANY PEOPLE.
This needs an end. I don't care how you gonna resolve it, if you gonna tell the GMs "Give the players the exp they lost" or any other way. Just do it fast and ONCE AND FOR ALL.
I'm gonna bump this until I (or that thread) get an answer.
