Basically been playing a lot, and now the last 2-3 days. 90% of the games I play, I see my guy block or parry, I hear the sound of it and see the guy get staggered from example parry, then next second he's going ham at me and killing me.

This has happened several times, in different scenarios.

Like I guardbreak them, see them stunned from it and next second they are executing me.

I'm executing someone, next second they lift me up (Shugoki) and crushes me.

I have 100/100 or "fiber" as people call it. Can't get better internet and had no issue before. Only these last days, where half the time I'm "Puuh, I won" from a hard duel, and the next second they killed me instead or I push someone down (Because they tried pushing me down) and then they come back up, pushing me down..

Best way to describe it is "Rollbacks" or whatever
