Hello, yesterday my coreserver was not working I had several crasheds, shortly after I resolved to the server in maintenance, a German entered my ts and said that he was "hacking my server", and went to look at the logs always stated this:

25/12/2018 - 21:08:27 (CORE: is not alive)

12/25/2018 - 21:09:19
OnPreJoin (): Account not found, ******** <- Account ID I resolved not to expose username

and the Server Crashed Log appears all the time:


12/25/2018 - 21:55:21
[CRASH] - DPSrvr.cpp: CDPSrvr :: OnDoUseItem (Ln. 3216)

Is there any way to fix it? Can you please give me a guide on how to solve it?
