Using Planet mods Maraxsis and Naufulglebunusilo.

Maraxsis requires Spidertron Patrols, which requires Spidertron Enhancements. Somehow when Naufulglebunusilo generates its surface, it uses Unknown Key tile-name.ammonia-lava. These tiles can not be paved over by anything.

I tried to get AI assistance in writing a fix,

if data.raw["tile"]["ammonia-lava"] then
data.raw["tile"]["ammonia-lava"].can_be_replaced = true
data.raw["tile"]["ammonia-lava"].collision_mask = {"ground-tile"}
end

However when I made that fix into a custom mod, it failed to start citing "Spidertron Enhancements" as the reason. I am NOT a coder and have no idea on any of this....Just reporting it in case someone smarter knows whats up.

Yeah that code uses the 1.1 API, it won't work in 2.0. It probably blames Spidertron Enhancements because Spidertron Enhancements assumes that other mods are adding valid things. Since you aren't then yeah it will error. It doesn't mean Spidertron Enhancements is actually to blame :)
