I have and interesting problem. I have a NPL licence issued May 1st 2014 and valid to November 6th 2014. Today after about 250 days of uptime my TS3 server crashed. Logs reveal the problem is an error which usually pops up if the licence has expired:

Server() error while starting servermanager, error: license date not ok
Im wondering why did it crash if no one was touching it and especially why is it showing that the licence has expired.
AFAIK even if there was something wrong with date (server date is valid) shouldn't the license be renewed for another 6 months?
