On experimental most the time I lose my character after a server restart (I think it's a restart although I don not see the "no message received in XX seconds" message but only "session lost" message.

Sometimes when I log in again I get a message saying " your character was unable to be loaded and has been reset..." but not always. Sometimes I see a message when the gam is loading that my profile was not saved because there was no connection with the central server.

This happens now 8 out of 10 times to me.
