Monsters stop attacking / Burning ground stops burning

Every couple Maps i kind of become "neutral" with the map/mobs.
Not sure if it has something to do with Headhunter or something else.

As the title says: Monsters do not attack me anymore (they might do if i would attack and not oneshot... not sure) but i can just run around without getting attacked.

Also: burning ground does nothing anymore.

And: Monsters that have to be triggered to actually "spawn" like some skeletons that lay around waiting for players to approach do not do their animation.

Bug fixes whenever i portal out and back into the map.

Just had this happen again... i think it triggered during the breach encounter.

it is headhunter buff yes.

so a bugged headhunter buff that does not really go away? because it stays this way even with 0 buffs remaining

Yes its a bugged buff.
