[1.5] Strategic Spells Cost Double
For some reason when I cast a city enchantment or any other strategic spell it costs double the amount that it should. For example, Propaganda should cost 20 mana according to the spellbook but when cast it reduces my mana by 40. If I'm not careful when I cast a spell it will take my mana negative and the next turn all my enchantments will be gone.
This problem is very repeatable. It will happen on the first turn of a new game. I don't have any mods and it happens with a custom sov or the stock sovs. I validated the files and it found two problems so I just uninstalled the game and redownloaded it. Unfortunately it is still happening. What could be the problem?
