SteamOS version fails to start OS: Ubuntu MATE 20.04 Specs: 24G RAM, AMD Ryzen 3 3200G with Radeon Vega Graphics × 4

I'm on a mac. Bought the game the other day after playing the online demo, and when I press play, it goes as if to launch (the Play button becomes Stop, etc), but then within a few seconds goes back to Play, with nothing ever having opened. I'm a bit lost as to how to fix this with no error message to go on!...

Just a suggestion. Sometimes I found it slightly difficult to distinguish between dice. Having color coded dice should remove this issue. Thoughts? Btw, great game!!

I'm at max draft level and have no clue as to what the second hidden ambition is. Found the Necromancer pretty easy, but I am lost as to the second hidden ambition. Can anyone give a brother a hint? Real head scratches for me. At least the necronomican was hinted at in the custom game with the ability to select necro and skelaton villages...the other one alludes me. Awesome game. Euro Game on crack....

I press Play, there is a Dos-window opening for a second and the disappearing. Then nothing. Steam says the game is running. But there is no game window open.
