[1.5.2] constant popup after winning

[ageofchaos]

So I finished killing the two endbosses with my shalore paradox mage in nightmare, and the popup for congratulating on your win and then the dialog box asking to leave pops up. I click on the only option (leave), and it just reopens the congrats and dialog box again. Tried like fifty times, same deal. So I terminated the game process, went back in game, and now I'm level 49 and on floor 1 of high peak. Gonna try a second time here, but that's a rather frustrating bug to get.

Did that happen again?
If so, I'd like the savefile please
