hi.
I really dont know if this really happens or it was my head:
i has almost all my army camps with an upgrade cost around 12M. i decided to upgrade one with a higher cost just to use the supercharge. After that upgrade, i think all my camps got their upgrade cost higher, around 40M.
This really happens or it was my head?
if this really happens, what caused it?
thanks.

Did you perhaps have the auto-upgrade-army-camps advancement enabled?

With the extra armies from the supercharged camp, you probably have captured a few money caches. And that money might have been spend upgrading the camps without you noticing it.
