Describe the bug:
Tectonic is supposed to generate specialty caves with lava rivers deep underground. However, with Spelunkery installed, the caves themselves generate properly but are missing the lava they're supposed to generate with. Tectonic developer confirmed the issue appears to be on your side. Images and more info provided in the issue post below.
