Someone has basically copied my account name (I am Nights_Watch5, and they are Nights_Watch589) which is causing my account to glitch, as since they have joined, I can't check my MTC balance, I can't Private message people, and people can't add me to there chests (/cmodify). Can someone please help, as this is really annoying.

Thanks,

Have Fun,

Nights_Watch5

ADDED INFORMATION: OK someone hasn't copied my name, it seems to be that every time I join, there is me and another thing/person/unknown entity with the same name as me, but there are two extra random numbers added to the end of it. I have no clue how this happened.

You have a clone.... You likely died in a world other than main (event, nether, end) and this has happened

It usually clears up during server reboot.

ah ok, thank you for clearing that up.
