Thank you for the report! It will be fixed as soon as possible! Added to our notes.

I also have this issue.  Level 5 Crusader, attempted my first tarot mission sucessfully, and upon completion I was stuck in the reward screen with the continue button being greyed out and unclickable. 

Same issue here.  I can alt-f4 my way out of the screen, but trying to enter the game again as that character brings me right back, still stuck.

The 'Continue' option is greyed out and I cannot click on it, despite having opened and examined the rewards.  I've tried clicking around - in case there were some sort of missing UI element - with no luck.  Co-op mission, my partner (who created the mission) was able to continue as normal - only I was affected.  Patch notes do say that 'investigation/tarot stuck' is a known issue, which might be referring to this?

No, was a solo run. I did create the Tarot mission while I was in a party... Never launched it as coop, though...

Did you guys do your Tarot Missions in Coop?

Same here. Can't get past the rewards screen after a few missions. Problem persists even after reconnect. Only option is to create a new character. First encountered it when I got a level up to lvl 7 with my crusader. At the starting screen it then displayed as lvl 9 already. 

I can confirm, I have the same problem. Nothing helps to get past, except ending the game's process through task manager.
