Short description of the issue and how to reproduce (is it random / always happens / side conditions ?)

If i put the plugin in my server after a player connects it crashes

Have you made any (noteworthy) changes to the default configuration of NCP?

No, it the default

Do you run any other special plugins that affect game mechanics next to NC+ (skills, machines, adding/changing blocks, other anti-cheating)?
