Annoying Mirage bug

I came across this annoy bug for the Mirage more then a few times now.

So what happens is it pretty much traps you in the Mirage area not able to leave and only way to do so is via force leave to character screen/log out and to log back in.
since the area it self is a no portal zone this is the only way around this bug.


There is nothing left in the area all cleared out, so its not mob related ect.

This is annoying in maps at times as it eats portals and costing time to log in and out as well.

Its not lag or anything as well along those lines.
