No I was probably just working on getting a rocket. I remember one time I was just sorting my inventory. However, I do think that I was trying to ride a helicopter from Flan's Mod.
I have been playing UMS with my friends for about 4 days now and yesterday 6/10/16 my game kept crashing around 5-10 minutes in no matter what I was doing. I have tried uninstalling and reinstalling several times but nothing worked. I dont know how to read crash reports so I'll let you guys do that. If anyone can please tell me how to fix theis problem I will be very grateful. Crash Report: http://paste.ubuntu.com/17226038/
