yup no idea why that happened.. logs show now, it just crashed and vanished without a crash report
this server build is really bad for stability as its not really proper 1.8 server which causes many weird issues with other 1.7 plugins so far i've had to remove a lot plugins... the only solution would be to go back to the last 1.7 server build and not bother with allowing 1.8 clients to connect.. then we could have more of the plugins back and server stability.
well that's the choice
