Endgame map wipes after dying to Map Boss (Bug?)

I was doing a T10 Map, and I cleared all ads first before doing any other map activities, I had delirium, expedition, and rituals and map boss. I went to go fight the Map Boss before doing anything else, i got killed by the boss but then i look at the top right corner the whole map just changed camera angle and wiped everything from the map. This happened to me before in a T5 map. I didn't really bother me when it happened the first time but this time my map was juiced and now, I'm just pissed. Please look into this I sure it has to do with map bosses.

"If you decide to rush to the Map Boss without interacting with any of the other Map content and then die, you will respawn at the Boss checkpoint and only the Map Boss will be present. All of the other monsters and content will be removed. This is to prevent cases where players would be able to farm multiple copies of the same rewards by dying on purpose."
