When you mouse of war productions and research the cost isn't correct. Often it completely ignores the state fund cost.
I work around it by jsut waiting until I have more funds, but it can be confusing.
Here is a screenshot of the research for tanks, playing as eastern entente.[ATTACH]30227[/ATTACH]
It shows the correct EP cost but ignore the SF cost.
I have experienced 0 crashes and find the game well balanced in all other respects.
Also what's the limit on HQs you can create? I send *** generals to my GHQ but he no longer allows them to become Hq leaders.
