edit: it is a Single player survival world. After relog i had the apiary in the hand world was fine. there is a sound muffler near the apiary, a few moments before the world crashed the sound was not reduced (there are 20 or so cows behind the wall....). Not sure if that is important. The crashlog implies a problem with the one probe it seems.......

Update to v4.3

Im having this problem also
It looks like you are using an unsupported modified version of the game.
The game crashed whilst tesselating block in world
The game crashed whilst tesselating block in world
Error: java.lang.ClassCastException: net.bdew.gendustry.machines.apiary.TileApiary cannot be cast to cofh.thermalexpansion.block.storage.TileCell

will get full msg when i retest this

Edit more testing and this seems to be a problem with thermal expansion storage cells (my problem)
removed the cell then broke fine
