As the title implies, I accidentally duplicated Ro Bin. I have seen this bug before but not like this. I picked up the Stone Egg to move to the fire but picked it up as it hatched. When I tried to put down the Stone Egg two Ro Bins spawned with two Gizzard Stones as well. The strange thing is that both Ro Bins have working inventories but only one will follow me to another room or outside the house. The other Ro Bin appears to be confined to the room he hatched in even if I bring the Gizzard Stone with me.
1. Have Stone Egg near to hatching 2. Pick up the Stone Egg during hatch animation 3. Attempt to place Stone Egg back on ground.
