• Created Productive Bees stone nest
• At the time of the bee spawn, world crashed and is not loadable anymore
• Crash report seems to indicate a problem with the digger bee

Update: tried in a creative world. It's not the spawning that does it, it's the full bee catcher. When the catcher is full of bees (9) the next bee it tries to catch crashes the world!
