I was trying to watch some of my replays to look at some things I did in game and then the bug happened:
At first I downloaded one replay and watched it, no problem, all went fine. But then I tried to download another one bug I was notified that an error occured. I tryed Again and again but the message (that bugsplat window) kept coming.
I thought the file was corrupted so I deleted it and tried again. Nothing changed.
I downloaded another one and the same happened.
Idk if everybody is having this issue, but you can try seeing it by downloading two replays and trying to play the second.
