Defense Nexus/Construction Squad-mate Lag

Was in Battlefield 6 RedSec Quads Battle Royale with random people as a squad. I was in Construction and another person was in Defense Nexus (Nexus). Only us two were alive. I was running towards Nexus when out of no where there was MASSIVE LAG for my squad-mate. They ran through the wall at Nexus and I saw it. You hear us talk it out on comms stating "I just seen you run, yo" and "I just lagged real bad". Not sure what happen here but I also have my PC stats up and it didn't seem to have a drop in FPS or anything like that just out of no where issue (go to 7-8 seconds left in video -- sorry my video editor is down right now).

I use PC (as previously stated). I believe they are on console, not sure which though.
