"Keeping entity minecraft:item that already exists with UUID XXXXX"
I keep on getting these spammed in the console that usually results in the server running out of memory and crashing. The item culprit seems to be Tallow from Quark and pigs.

(I seem to be getting this problem after installing Psi 1.1-69 or it could be after we entered the twilight forest)

Enclosed is the latest log.
