So I was playing a Tribute match today on PS4. I started getting odd pop ups in the top right corner saying something along the lines of I couldn't start a tribute match because I was already in one. Then, the game got really glitchy, and at the end of the match my screen hard froze for about 10 seconds. When I came back, I had close to 10 whispers from my opponent that were commenting on plays in the match, and seem to have been sent while we were playing. I asked them how they whispered me during our match and they replied "idk". The whole thing seems odd, I haven't been able to replicate it myself and don't know how they could be messaging me during a tribute match, but I am also concerned because it did seem to contribute significantly to lag in the game, and seems like something that could be exploited.
Anyone have any insight?
