Expedition Logbook bug

I opened an Expedition Logbook. Found the area had Orloth. Went in the boss arena first thing, without killing much mobs, killed the boss (everything seemed fine).

When i got out of the arena to finish the rest of the map, i was killed by a monster (-.-)

After i pressed "Resurrect in Checkpoint", loading screen occurred, was resurrected inside the boss arena (whereas my last checkpoint was).

After emerging for the second time from the arena, the map was void of monsters, no chests to open, no dropped loot.

Just an empty map with only the expedition NPCs present.

I would like to mention that the "death menu" said i had 5 more respawns before pressing the "Resurrect in Checkpoint" button.

Don't know if this is a feature, where you get only 1 shot to do the expedition if there is a boss present, or no boss at all just overall 1 shot per expedition logbook, or if this is not intended to happen.

After this happening i did /bug. My bug report reference number is 1.619.185.143.
