So last night we updated our servers to 1.9.4 and we are experiencing some weird bugs ever since... Both of these bugs seem to be chunk-specific, but some players just flat out have chests that are now empty and I have to roll them back and restore them in order to get their items back. One player had a large storage area that spanned 2 chunks, and only the chests in one chunk were empty, and the rest were fine. Really odd. And the other bug is affecting certain players' item frames... They basically keep coming back and falling onto the ground every time the player leaves the chunk and comes back. When I tested, I would break 2 item frames with items in them, leave the area, and when I came back they were duped and back on the wall and would fall after a few seconds on the ground. Quite a nasty little dupe if abused... Anyone else experiencing this after updating to 1.9.4? I have had reports of it on my Survival and Skyblock servers so far as well. Hope to gather some info and figure out what's causing this. Thanks! https://hub.spigotmc.org/jira/browse/SPIGOT-2280 EDIT: Here is a short video of one of my player's item frames that is stuck in an endless duplicating loop. Her chests that are in the same chunk also ended up completely empty, despite having items in them prior to updating to 1.9.4... I also ran these same tests with the same server/world with ZERO plugins enabled, so I know it's not a plugin issue. And to reiterate, this bug has also occurred on our Skyblock server as well, and is not just specific to our main survival server/world.
