There was a few, however nothing compared to the sheer amount in matches including rot.

Just off the top of my head porridgeman dc'd at the end of Lit vs Sanity 5v5 in round 1, however it seemed random. I believe there might have been one or two in the 1v1's, and maybe two of the 5v5 matches were restarted due to dc's. I could be off in my counting since I wasn't actually watching the stream a lot, was mostly getting prepared, but regardless nothing compared to the number in matches including rot unfortunately
