Game crashes when i open barrel, saying the game crashed whilst ticking block entity - and The game crashed whilst ticking block entity
Error: java.lang.IllegalStateException: POI never registered at eu{x=77, y=68, z=12}

try the world, it will crash if you open the barrel

unloading chunks and load them again will stop the game crashing when opening those barrels

another test has shown, that it crashed again, i must do some serious testing
