Major "desync" issue when grouping (commanding HoT HP Trains and running JPs)

I command HoT HP trains daily and lately players tell me they see me desync. Basically they see me go in a different direction than I'm actually heading. Some say it's a mount bug. Yes, I was on a mount at that time. On my side of things, everything is good. I have no lag, no issues what so ever. So for example, when going to do the Golem HP in VB, how you run up that spiral at the waypoint; I fly over to the big vine and now I'm gliding to golem, I see my squad waiting back at the top of the spiral at the wreckage. I ask them what they're doing and they reply stating they see me running in to the wreckage. That's just one example.

I don't know what I can do differently. Like I said, there is no issue on my side b. Just a moment ago I was guiding a player through Scavenger's Chasm JP to collect all 12 orbs. Initially they were following then they jumped down. I asked what they were doing and they said they were following me. This happened multiple times; to the point where I had to call off the JP off because I was porting on them on CD. This player kept seeing me go down when I was really going up.

Again, I don't know what i can do do differently. Is this a known bug? If so, it is being looked in to?

I appreciate anyone's help. Thank you so much.

I run JP tours and can tell you something is going on people who look like they are far away tell me they are right next to me. It really messes up the process of porting people. I don't know who needs saving while in squad. I hope they fix this issue.

That happens for me as well. Guildies desync on map when doing open world events. It has been so for weeks.

Looks like GW2's client side prediction is broken.
