Earthlike AR planets shouldn’t, and in my testing today didn’t, have any rocks or sticks generate. Same goes for Twilight-like and Atum-like, since GT checks for them by dimension.
The Erebus is checked for by biome, so rocks do generate in those biomes on AR worlds.
The AR space and moon biome worlds are working just fine, with the right rocks and large veins. Although I was actually surprised when I finally found a vein as many of those veins can generate above ground (and thus disappear).
