Yes all admins said that nothing will be lost in full game except for leaderboards. There is a million threads abou it.

Hmm, not good enough because they said million times for the shared plats issue and see how it goes now.
Besides, you can't find one single thread that say they ever mention about this shared plats stuff. Try search it out.

...The only thing being wiped is out kills,deaths, and leaderboards...'nuff said.
