Teleporting exiles

Edit: Accidently posting in technical, was meant for bug reports. sorry :-/

Playing on ambush league, a constant and fairly annoying issues is with rogue exiles spawned by strongboxes teleporting around wildly. If you kite an exile away far enough, he will randomly disappear and spawn next to the strongbox that spawned him. A couple of times, I've seen exiles reappear next to me, but mainly they simply warp away.

Please note that this is not the omnipresent desync. You can trade blows with the exile, /oos and everything is fine - the next second he is gone. This does not happen once in a while, but pretty much every time.

I have seen this happen to other monsters spawned by strongboxes, but no where near as frequent as with rogues.
