Using 0.3, with GeoStrata in the pack, I receive this error during chunk generation. Without GeoStrata, works fine. Cross posting on both issue trackers.

RTG and GeoStrata have always played nicely together. I just generated a 40k-chunk map with both mods installed and everything seemed to be fine.

I suspect this is an issue with Harder Ores and GeoSrata, but I'll leave this open in case it's something on RTG's end.

Any luck getting to the bottom of this one @Haggle1996 ?

No, I haven't had time to dig back into this, with the holidays and end of year work.

No worries mate - I'll close this for now as I'm pretty sure it's not related to RTG, but feel free to re-open or create a new issue if you need to.

Just replicated it without RTG, so confirmed it's not RTG. :D It does happen much more frequently with RTG, FWIW.

👍 Noted.

Hope you get to the bottom of it!
