Srever dropped me and I lost my map

I thought, if the server dropped me, whan I logged in again, I would still be able to access the map I was running. I just lost conact with the server while right at the end of a blighted map and when I reconnected, the map was no lonegr available. How come? Can I at least get my map back?

The instance crashed which is why all the portals disappeared. And GGG will never refund lost items for any reason ever.
