Fix race condition with chunks, dead tile entities Fixes PaperMC/Paper#883 same issue as MinecraftForge/MinecraftForge#4386 A more detailed anaylsis of what is probably going on, courtesy of @bs2609 and the MCForge Issue Tracker is: When a chunk is unloaded, the entities and tile entities it contains are marked for removal. The actual removal (from the world) occurs later, when the world ticks its entities. Conversely, when a chunk is loaded, it generally adds its entities to the world promptly, without queuing. Here's the normal sequence of events: Chunk unloaded Old entities removed Chunk loaded New entities added However, what can happen: Chunk unloaded Chunk loaded New entities added Old entities removed This occurs when an unloaded chunk is reloaded before its corresponding entities have been removed.
