No problem, Geez. I'd recommend contacting Deus_Vault of the 69th Lowborn Brigade, as he may have logs from that day that could aid you in the process of finding it out.

This sometimes happens when you flip a car a get out from it. This somehow desynchronize your body on the server. For you everything looks normal, for anyone else you are invisible just like on the above video.
This is most likely related to T165746.

@lipek is right @Geez I confirmed this by doing it last night, it also keeps your comms local to your body now when before it allowed you to walk around talking to people as seen in my video.
