Rollback (?) after a map crashed.

My map lagged and ping started going to infinity, so I just pressed ALT + F4. When I logged back in not only portals were closed, map was marked as "attempted" and the breach, boss and irradiated that it originally had, were gone (so basically as if I failed the map), but also my inventory was cleaned of all items I looted before I "crashed". As if it had rolled back to before I first entered it. Waystone I used to open the map was of course gone.
