Maybe GalaxySpace's Ores (like sapphire ore,mars aluminum ore,mars gold ore and so on...) can not gen on Galacticraft's Planets,I can't find them everywhere.How to solve this problem?
GalaxySpace version 1.2.2
Galacticraft version 3.0.12.503

Maybe you disable ore gen in config?

Well,I reset the Galacticraft config and the GalaxySpace config, but it still can't solve the problem.In my opinion,maybe Galacticraft disable the ores from other mods gen on its planets by default.

The problem has been solved.I enabled custom oregen configuration in
.minecraft\config\Galacticraft\core.conf
This is a reference:

If you think this is reasonable,you can close this issue now.

Now the problem has been completely solved in GalaxySpace 2.0.8.
