I also reported some bugs after the intial post.The first one
was fixed. The second one
is not fixed. This is Mint/Innovation. I tried now, game 30743535, turn 9. Here I actually had 3 when-buy abilities: Mint, Haggler and Charm. I don't get to choose Mint before any of the others, which is also a bug. The important thing is the gaining of Crown (from Charm). The Crown is played via Innovation. In the end Mint resolves, but the Crown is not trashed. Crown should be trashed. And this is why you should be able to resolve Mint first.The third post
reports of interactions that work, although it's displayed in the wrong place in the log.
