I suggested a commercial pact with an inferior empire and it shows this:
I will get 50 energy, they will get 4. But that's wrong. I'm a vastly bigger empire and the values seem swapped. And I got mercantile traditions for the goods and unity.
After it was accepted I got this popup:
This time they will get 41 (10 zones more). The values are not right?
I only got about 5 energy more next month. Didn't check unity and goods but this Toby empire can't give me such a huge amount.
