suffering this on our server
Whenever someone gets in the Harrier everything starts to Desync - people despawn from the Harrier and everything quite literally warps back to normal.
Someone gets in the Harrier and you've got aircraft flying at 90 degrees to direction of travel or in vertical climbs upside down and all kinds of weirdness.
Clean install - no mods - only two harriers in the mission, no scripts or anything and it happens every time
