Changing civic is too much expensive... bug?

[spad85IT]

Situation:
I'm German, I've conquered a continent and I decided to change from Banditry and Republic to anothe military civic and Federal.
When the anarchy ended I passed from +200 to -900.
"Maybe I choosed the wrong civic" I thought. So I changed the military civic again. And I passed from -900 to -1500/-2000. I changed to the original civics again (Banditry and republic) and the situation worsened...

Basically every time I change civic (indipendently of the civic!) my economics get worse.

In 5 changes I passed from +200 with 70% research to > -2000 with 0% research.

I had to reload before the first civic change and keep using Banditry and Republic

Anyone can help me?

How many units do you have?

Hmm... many about 320 units.

Anyway I don't think it's a problem about unit. I mean... I change from a situation "A" to a situation "B" and I lose a lot of money. Why if I change back to situation "A" I lose much more money?
