In Injection's case, I can see him announcing on the chat that he was going to leave because of lag issues, I can see Fullfilled saying the same thing too, and they play from the same place, so I'm going to assume that Injection did not do it on purpose and he had infact internet problems.
In rami's case, he seems desynced since he's shooting at a wall, although I can't tell for sure with screenshots only. Sorry Bhai but this is insufficient proof. Please try to grab a video next time.
