It has been awhile since I've played the game last. At least since about a week or two after the last big update. But the other day I saw a new update up and got it then decided to try to play the game again.
The peculiar thing is now the game is making me pay 4 times the materials for my units (I don't remember if it made me pay extra for buildings). I don't have a save because I didn't save the game. I would start up a game real quick and save it, but I'll have to wait til later because I'm on break at work.

So basically it makes me pay quadruple materials. Everything else is fine. Occasionally when I go to the training menu it shows the right materials (but if I click on something to make it, it still makes me pay extra). Sometimes it'll pop up right when I go to the design menu and come back. The materials displayed on the design material when I make a unit are correct, though.
I didn't think this was part of the update and don't really know if the update itself is the problem, but it just started showing up. But I haven't played in awhile... so I could have had the problem awhile and not noticed it. I tried searching the site for similar problems, but didn't find anything (though I didn't have much time to search.
Oh and sorry if there is not enough detail. I'm kinda pressed for time at the moment.
