Hi orzelek,

can you add exception/support for FossilRoots?
Now this ore have same places as vanilla trees:

data.raw.resource["fossil-roots"].autoplace.order = "c"
data.raw.resource["fossil-roots"].autoplace.control = "trees"
data.raw.resource["fossil-roots"].autoplace.sharpness = 0.9
data.raw.resource["fossil-roots"].autoplace.richness_multiplier = 1500
data.raw.resource["fossil-roots"].autoplace.richness_multiplier_distance_bonus = 20
data.raw.resource["fossil-roots"].autoplace.richness_base = 20
data.raw.resource["fossil-roots"].autoplace.coverage = 0.01
data.raw.resource["fossil-roots"].autoplace.peaks[1].influence = 0.5
data.raw.resource["fossil-roots"].autoplace.peaks[1].richness_influence = -0.5
data.raw.resource["fossil-roots"].autoplace.peaks[1].noise_layer = "trees"
data.raw.resource["fossil-roots"].autoplace.peaks[1].noise_persistence = 0.6
data.raw.resource["fossil-roots"].autoplace.peaks[1].noise_octaves_difference = -0.5
data.raw.resource["fossil-roots"].autoplace.peaks[2].influence = 0.25
data.raw.resource["fossil-roots"].autoplace.peaks[2].richness_influence = -0.25
data.raw.resource["fossil-roots"].autoplace.peaks[2].noise_layer = "trees"
data.raw.resource["fossil-roots"].autoplace.peaks[2].noise_persistence = 0.6
data.raw.resource["fossil-roots"].autoplace.peaks[2].noise_octaves_difference = -0.5
data.raw.resource["fossil-roots"].autoplace.peaks[3].influence = 0.625
data.raw.resource["fossil-roots"].autoplace.peaks[3].richness_influence = -0.625
data.raw.resource["fossil-roots"].autoplace.peaks[3].noise_layer = "trees"
data.raw.resource["fossil-roots"].autoplace.peaks[3].noise_persistence = 0.6
data.raw.resource["fossil-roots"].autoplace.peaks[3].noise_octaves_difference = -0.5
data.raw.resource["fossil-roots"].autoplace.peaks[4].influence = 1
data.raw.resource["fossil-roots"].autoplace.peaks[4].richness_influence = 0
data.raw.resource["fossil-roots"].autoplace.peaks[4].noise_layer = "trees"
data.raw.resource["fossil-roots"].autoplace.peaks[4].noise_persistence = 0.5
data.raw.resource["fossil-roots"].autoplace.peaks[4].noise_octaves_difference = -1.5

(this part was generated procedural)

I can add ignore to it so that RSO doesn't produce error messages.
But RSO doesn't support ore generation aligned to trees. It might not be possible to fully support it unless it would be turned into normal ore.

So, can you leave vanilla ore generation for this ore?

I will add an ignore for next release so RSO will stop disabling it from placing.

Thanks!
