Unions

[KaMiKaZe 24]

The unions are bugged because when you ally with someone, if you in the next turn click in Union, it will work, even with countries 10x bigger than you (Sorry for bad english :v)
(But u need at least 10 provinces for countries 10x, and same ideology :D)

Unions are just generally broken.

I do not think it work, unions are so delicate to do, sometime I have 100 relations and alliance and civ still refuse union.

It is totally normal that you unite with a country bigger than you.

Example: Russia and Belarus.
