why i die??? and omen not actived

Knowing the early access of the game, some small bugs are acceptable to some extent, but the most frustrating thing for me is dying without even knowing why I died. I had already cleared a map irradiated with delirium, there were no more mobs, I was just getting the loot from the level and out of nowhere with no explanation I died in a matter of 2 seconds without knowing why or how. I recorded the replay if necessary, it is also frustrating that you play 10 hours to get 10% XP and end up dying and losing practically 10 hours of life. There is an omen that prevents losing 75% of x, but when I actually died, the selected omen was activated and it did not activate and I lost the xp that I took so long to get. I believe that this "loss" of xp at the final levels - 90 + could be reduced or canceled (I also have a video showing that the omen did not activate upon death.
