Ok thank you for the heads up. Was wondering what was going on :3.
Belive me - in the first moment we thought we fragged the 1.8 server with the scripts.... and then the mainserver too after we neither could log in there - cool sweat for a few mins... World corruption? Both servers? Oh my god...
But no - Mojang just screwed up again, hehe! Next time its the first thing I will check!
Lesson learned: If something screws up - blame Mojang!
