So I have this world where I use trip wires for a witch farm. After awhile of the farm running the trip wires get stuck on (even if i destroy and replace the trip wires). When you save and quit and then re-enter the game its fixed. I can't find anyone else having this problem and its not my world as I made the same farm in a fresh world and had the same problem, I couldn't find a way to repeat it, other then just letting the farm run for awhile. The time fluctuates. I believe this is caused by and entity that isn't there anymore but still triggers the trip wire. Much like a ghost entity. I might be totally wrong however.

This bugs not fully resolved properly. The route of the bug stems in parts of the entity update code that haven't been fixed yet. The reason tripwires permanently stay on is related to ghost entity's existing in the chunks but not added to the global entity list. Any form of ghost entity needs to be caught and throw a proper exception in the console or give any hints or warnings that entity's that aren't properly added to the correct lists exist in the world. If no exceptions or warnings are sent then any bug creating ghost entity's can cause memory leaks and other issues as they can build up in the loaded chunks indefinitely without being handled.
