Nobody comes! No raiders, no claws ... (Fallout Shelter)

Received the task: "Kill 9 creatures with bare hands (raiders)". Everything is not bad, it turns out 1-2. Gives the task "Survive 10 attacks of Deathclaws without loss". And the 3rd task: "To live 10 hours without losses." All tasks with boxes, but after spending 2 hours in the game, no one came! How about 2 hours? During this time: one fire and 2 times cockroaches got out ON HARDCORE! I have no words!
I'm going to download the fallout 4 pirate ...
