1. I Placed a normal electromagnetic plant
2. I go into the Map and insert 5 Modules ghosts into the plant
3. I place a legendary electromagnetic plant over it in the Map
Case 2:
You can replace the normal electromagnetic plant with a Assembler 2 and the legendary electromagnetic plant with a Assembler 3 and the same thing happens.
What happened?
The normal electromagnetic has an upgrade order to legendary but the Module ghosts are gone
What did you expect to happen instead?
The normal electromagnetic has an upgrade order to legendary and all the Module ghosts.
The same as I replace the electromagnetic plant per hand.
Does it happen always, once, or sometimes?
It happens always.
