When I load my savegame with this "unlimited resources everywhere" I get soon after start:
Error while running event OreGalore::on_chunk_generated (ID 12)
OreGalore/control.lua:27: attempt to compare number with nil

Sorry for the error. I think I know what the problem is and I think I fixed it. Please let me know if you encounter the same error. Thanks!

I am also having the same issue... I love playing with this mod, but when I load a save state it says the same thing...

works now, thanks. Will be fun to get rid of unused ore...
