not sure if this was due to the lagspike I underwent before crashing, or if this caused the lagspike, but at the end of the log theres:

[22:16:42] [main/INFO]: Warning: Clientside chunk ticking took 205 ms

Do note, my system isn't exactly some glorious gaming setup. 2.0 ghz of CPU and 6 gigs of ram dedicated to minecraft might be the cause of this issue, but I figured I'd listen to the crash log and report it anyway, just in case my abhorrent setup wasnt the cause of this crash

Its normally a system issue, at some point I will look at the populating code and see if we can improve it. For now I will be closing this.
