I was playing on server DE-02 (126.96.36.199:2502) when it crashed at 1:32pm.
At 1:33pm my client crashed while I was trying to join server DE-02.
I launched my game again and when I attempted to join DE-02, I got the "Character Loked in database" error.
I waited for 5 mins then tried again to join the same server, but with no luck (I either had "Character locked in DB" or "Connection with host has been lost" error).
Hope it helps
