1. agreed
2. "accidentally damage a police car" ...how? ...and why place a bedroll near it before?
3. not sure what you mean there. What "modes" do you mean, and what is "Zombie Crazy Horde"? Do you want more options to sort of configure random wandering hordes?
Isn't it already adjustable how many spawn and what number?
4. Yes, that's an almost inevitable thing and TFP cannot be blamed for it. They code the game ("vanilla") and can't consider compatibility of mods when they code/release a new game version. In fact that has to be the other way round, the mod developers have to adapt their code to work with the newer game version.
If it would be the other way round, development of the game would be severely slowed and could never reach the goal the developers want.
You would have to wait for your mods to be adapted...or just try to reinstall them.
It might be just a problem with your game installation when you just updated the game without clearing the mods which prevents it to function correctly.
5. You are already using mods, so why complaining about the vanilla map generator being insufficient. Use an alternative one.
