why does my character in halo 1 stop moving

it stops moving and i can’t shoot or hit but i can look

Interruption of the connection to the host. I think.

The coolest incident of this was for me was in Snipers on Damnation. Terrible host - super laggy. All 4 of us respawned in the same room (the one connected to bottom snipe via the tunnel). None of us could move. Then, there was the sound of a single sniper shot, and we all died simultaneously.

Awesome.

Happened to me in co-op
