+Subject: [PATCH] Fix Non Full Status Chunk NBT Memory Leak
+
+Any full status chunk that was requested for any status less than full
+would hold onto their entire nbt tree and every variable in that function.
+
+This was due to use of a lambda that persists on the Chunk object
+until that chunk reaches FULL status.
+
+With introduction of no tick, we greatly increased the number of non
+full chunks so this was really starting to hurt.
+
+We further improve it by making a copy of the nbt tag with only the memory
+it needs, so that we dont have to hold a copy to the entire compound.
