Game Mechanics: Zoning, player positions

[Breachin]

Occasionally, when I zone into a zone, I see players that have entered the zone before me at the zone line even though they have already moved away from the zone line.

This normally doesn't affect me, but tonight I opened a trade window with one of these phantom players and the trade instantly cancelled and my item poofed.

Posting in petition forum as well in hopes of reimbursement.
