I made sure that this is not an issue here.
I tried just before exporting to make sure it wasn't a one time issue. It's still not working. I tried swiching the parts that are connected to the factory and nothing, it's just like the game don't like this particular drone. Again, I tried possibly everything that I could've been done inside the game. That's interesting to say the least. If you guys have any suggestions, please let me know.
