I found the cause of your problem, it was a mistake on my side, sorry!
Your player information wouldn't save due to an error I made when editing the database table. Your characters still saved because they're saved in a different location. Go join the server and post here/ask an administrator in-game to get whitelisted for the last time – everything should save fine now.
EDIT: You should get your donation benefit flags as well when you use /Benefits. You'll also get those 500 tokens by using that command - they'll be given to whatever character you'll be on when using that command. Please let me know if we got this issue solved or if the issues still persist. Thanks.
I have the same issue ever since about 2 days ago where my MPF char keeps getting banned.
I believe it is ever since I tried to fix my forum access after creating my ota unit who caused my mpf forum access to screw up, and thus required me to rewhitelist myself.
And ever since then, my character keeps getting banned when I join the server.

Must be a different bug. I'll try to have a look on it as well.
