About a week and a half ago I got on my pterosaur (from the Fossil/Acheology: Reported mod) and my minecraft crashed. Whenever I rejoined the server after this I got sent to the main lobby. This kept happening. I got my friend to come on to see what was happening. So my friend got on and he saw that I would join onto the server for about 5 seconds and then I would get kicked. So he killed the pterosaur in these five seconds thinking it would kick me off, but it didn't, and now I am stuck, and keep getting kicked. I really don't want to loose all of my player data and claims because of the two week limit so please help...
