I am misremembering, but in the past when you exited the rig your didn’t your toon appear where the rig was when you exited? Seems like since they fixed the rig in a recent patch I am getting and alter time-like effect to where when I get booted from the rig I am back at where I was when I entered the rig. This is when the rig time expires and you get booted. I am not sure this occurs when exiting manually.
I have died a couple of times because I would get tossed into the rig just as a fire pool or whatnot would appear under me and the rig expired I would get tossed right back onto the location and then die as the hazard was still there.
