Loos like the explosion presets are tuned for regular world gen/height only, so if you generate a "Tall Cities" variant, you end up with a lot of smaller looking holes always low to the ground.

The result are building that look like they shouldnt be standing or buildings with holes in them a la the 1990s Godzilla movie.
Godzilla walked through this!

Probably on your list of to dos, but thought I would mention it.

I'm tweaking values in the configs and will share some adjustements in case you want to use a different set. Might be useful to have command that reloads configs without restart.

As I mentioned, here's some values I seem reasonably happy with.

Thanks. I'll include them for next version
