Client crashes when I teleport back to my base, might be a duplicate or might be architecturecraft's fault, I do not know, please point me in the right direction.

Crash Report: http://pastebin.com/VgcCCqUT

Its agricraft, part of the reason i pulled the build from curseforge

I don't think it is, I tried without agricraft and architecturecraft and still get the same crash, but feel free to re-open if you think it's still relevant.

Ah no it actually is architecturecraft, you are correct.
