Step to reproduce:
- Create a new world (sandbox or use cheats to get the items) or open existing world
- Place one of the setups as shown below
- CtrlZ OR Remove the power pole and replace the ghost again
- Place it again in the same way
- CtrlZ
Setup for 1x1 power pole: A power pole must replace a the ghost of a different type of power pole (aka metal/wood) Setup for 2x2 power pole (large pole/substation): Replace the ghost tile by moving one block on either side Setup for 1x1 + 2x2 power pole (a mix): A mix also works, as long as the pole replace the ghost (a 2x2 must cover the 1x1 tile or the 1x1 must be within the 2x2 tiles when placing)
