Hearses are not sent out of cementeries. When I click on the building, I can see the cementery is trying to send out hearses but the counter jumps to 1 and then quickly back to 0 over and over again. Ruined my whole game because there are corpses everywhere...

Flickering between 0 and 1 vehicle indicates a path-finding issue. I noticed you have a lot of one-way roads, especially just in front of the cemetery. I turned most of your one-way roads into two-way roads and the cemetery started spawning hearses to pick up the dead. I'm not sure if the issue is just the roads in front of the cemetery or in other parts of the city too, but I'd switch all the one-way roads to two-way where you don't need them to be one-way.
