Turtles all unbreakable in survival mode, but no problems destorying them in creative.
Tried with both types aswell as before ever turning them on, with or without peripherals equipped or items in inventory to no avail.
I noticed however that turtles have no problems "digging" other turtles, something is going on?

no mention of anything in logs - can supply if requested
Simply place down any turtle in survival mode and try to break/destroy/mine them, with or without a pickaxe ect. It works in creative but not survival at all.
