I'm at a loss ... When I try to modify the inventory of a chest in the nether or end while no player is around, it often reverts to state before modification once I go back to the nether/end. I can verify that the change does persist until the point that I go back to the nether/end. It does not do this all the time, however, and it doesn't seem to happen at all in the main world or multiverse worlds. I've tried the following: - call the BlockState.update() method on the chest after changing - load the chunk the chest is in before modifying - save the chunk after modifying None of this seems to work consistently. Is there any other magic I should know about, or is this a legit CraftBukkit bug? This happens with 1.4.7-R1.0 and older versions. I feel the urge to bump.
