Lag Issue Returns

The lag/latency issue I posted about back in Season 1 is back again. 

Whenever I'm in a party, every skater is out of sync with mine. We have Limited Party Collision enabled to avoid passing through each other when we clip videos, and there are times when I'm not near someone in my party but on their screen I collide with them; or on their screen they aren't near me but on my screen we collide. 

This is especially frustrating when trying to clip a video with others in my party and while we are grinding, on my screen I pass in front of them with plenty of time to avoid collision but they seem to collide with a phantom wall of some kind, causing us to restart the line.

I've provided video of the same exact run on the halfpipe at Rolling Waves Skate Park just like in my previous post regarding this issue and hope it can provide the information needed.

Just to clarify:
This happens every time I'm in a party regardless of who I'm in a party with.
It happens to and with everyone in the party.
