I started a new game after updating and dealing with the loading screen crash with my previous vault. So far, so good. Have 22 dwellers, no glitches or crashes so far (maybe) but as of yet, there has not been a single raider or any other vault intrusion event. Zero. My previous games they were incredibly common. I get fires, rad roach incursions, but nothing and no one from outside the vault door. Anyone else experienced this after starting a new game in 1.1. Is it a level trigger?
