Bug: The adoption of the WTB-plan still doesn't work. If you have wtb support at 2 save, and test it a few times, sometimes you get it adopted, sometimes you don't (this also applies to the left plan and probably also the reformist plan so I think it's a quite serious bug). If you change an advisor before the card shows up it sometimes starts working.
My theory on the problem (this might be completely wrong btw): The card checks the requirements when it shows up, but it doesn't "see" the wtb support (or left support or reform support) until you change scene maybe? Not sure about this since going to the library or doing another card does not fix the problem, only removing (adding?) an advisor.
