Breach Crashed Map

About 3 seconds into a breach on a Vaal Foundry map, game hung despite stable internet connection. Esc'd and logged out to main menu, on relog, came back to no map and 0 loot from the other 98% of the map. Atlas shows area as attempted, all juicy mechanics wiped.

Bug ref: 2,574,670,612 but I'm sure not how much it'll help as it was pulled after I relogged.
