Nah it's my fault and I apologise, for the first 30 minutes of the patch if you rerolled before 9:30 EST Yesterday [ 1:30 AM GMT ] and lost PvE skills, I will personally fix your problem. Just find me on irc or ingame using the ~help command. Yesterday I've gotten at least 30 ~help requests to fix their characters and I will continue to assist with players today when I am back on.
For all those that rerolled after the second patch 9:30 EST till 12 PM, the only thing that I forgot then is Lifegiver and Deadman walker + Level 24 + characters. This can be fixed by simply rerolling again without the assistance of any GM.
Currently, there are no more reported issues, you're level drops to 24, so use all your skill points then. As soon as you hit anything for experience you will immediate get back to the level you were before as well as get your post 24 skill-point.
Regarding traits and gained stats via perks, the system accounts for the SPECIAL, such that if you have gifted and rerolled 5 5 5 5 5 5 5, it will put you to 6 6 6 6 6 6 6. Same goes for all the other traits.
