What do you mean by causing a black screen? When you level up with unspent points the entire screen goes black? Or is the UI visible?
Did you try verifying local files for the game?
If you have a save just before this happens, please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool.
I'll also try that my next game, and see if I have a problem...
Hey Raze,
Yes, i think i did...
I think i have the same game before that bug happen...
It like the bugs starts when your 2 main characters are at lvl 5, your companion lvls up to 6 but you don't use the stats points when you lvl up and then when your main characters lvl up 6, it cause the the screen to turn black but the UI is visible and music is running but can't exit the game or anything

Oh yeah the analysis tool for Divinity Original Sin, just crashed when trying to get data...Is there another way to send the data to you?
I'm using Windows 8.1...
-update-
It turns out that i pointed the analysis tool at the wrong directory and that caused the crash. Already pointed and set it to the right directory sent the report info..as well...
