mining turtles seem to duplicate when moved with the carry on mod in valhasia 3 after placing it the turtle is invisible right clicking it will cause a duped turtle to spawn on the block next to the invisible turtle right clicking fast causes a crash. oddly enough after reloading the save i was carrying a turtle instead of a mining turtle. also it dupes what ever is in its inventory when you pick it up

I've filed a bug on carry on (see above), which should resolve this when fixed. Tracking the cleanup I need to do in #658.
