I did try generating a world, then go into the save folder and delete all prefab entries.
It worked fine, until the trader quest. The game could not find a trader, so it gave me
red console errors.
I solved those by adding in a trader from a none-edited prefab file. That makes it 1
trader in my world, but i will have to live with that, and just not use it.
Experience so far, too few zombies in the world itself. Food is not an issue yet, i killed
some snakes, 1 rabbit and a chicken and got a bunch of eggs. Terrible RWG, spent most
of day 1 to find a green forest. Only on night of day 2, but doing long days. Might go with
shorter, 60 or 90 minuts since i don't spend much time looting.
The burnt biome seems to come with the burnt out corners as part of the biome, so these
are still present. As well as cars along the road and in the wasteland biome. And trash.
This allows for a little bit of looting, and has given me a cooking pots, a shotgun+4 shots,
and a couple pistols that i trashed. Also getting seeds from the trash and burnt corners.
Apart from the lack of zombies once an area is cleared, it's not too bad. Slow, but that
was my choice.
