For some reason, Dust Wastelands are generating in the Atum dimension from the mod of same name. Note that it has a river-like shape, so this was probably meant to be a Dried River biome instead, wich is highly probable because when I type the command /locatebiome atum:dried_river it says that no biome of this type was found. I don't know what is the cause of this, but this is weird.
