I mean limits on number of commercial agreements and state visit cards. While seemingly these feel unlimited, there is a limit on how many you can do within a period of time.
This has been going on for 3+ years now. I even cancelled a commercial agreement and that didn't change anything. No ability for state visits or commercial agreements.
Lincoln is now president in 1861 and I have state visits again. But no commercial agreements. Lincolns stats are 7 3 5. Could it be that the previous president Buchanan's stats that affected my diplomacy actions? I think he was 5 2 ? ..
