This is already posted in the TFR forums, but I figured it should be posted here as well.
There was some type of issue with the recent update that put the level cap to 23. If you log in with your epic you might have an issue with XP loss.... if this happens, just take a screen shot to document it.
I logged in with Akkori this morning but never left the OOC room; there was no xp loss. I'm not sure if this will be the case with everybody, but if you do happen to log in with your epic, just don't leave the OOC room and you might be ok.
