Issue with CapitalShipMaxTrainableLevel
So I was modding a mod and it had not trainable levels. I couldn't find CapitalShipMaxTrainableLevel so I just added the research to the mod and it auto added 3 levels. Problem is, when I get to level 3 and go to level up to 4, it gives a negative cost of 21718543698. Clicking it sends my credits to a permanent 1 and levels the ship up to the next level.
Any thoughts?
