Affects Version/s: Minecraft 15w39b, Minecraft 15w39c
Fix Version/s: Minecraft 15w40a
Noticed this after the issue with
MC-88922 and tried teleporting to specific UUID's to figure out the problem.
I'm not sure if it only effects old worlds as I can't test it atm but I have seen other people with the same issue on the other issue mentioned above.
Steps to reproduce.
Load up world in 15w39a-c.
open log to find a MinecartChest with UUID duplicates
Teleport to said UUID
See items on the floor.
This is a pretty big issue as they duplicate consistently and cause a load of tick lag.
It may only duplicate on load/unload haven't been able to test that either.
