I've been leveling a Psyker and up until yesterday it was business as usual. When I logged in today, I'm suddenly having an unbelievable amount of warp/insanity issues. Even when not at full warp heat, the warp monsters, explosions, and those warp chains that chase you are constantly spawning making the game virtually unplayable. I've just hit level 54. No gear changes from yesterday that I can see causing this. Very annoying. Hope it's just a bad hotfix that needs to be refixed.
