If this mod is installed alongside Prometium Processing (FG) the Promethium Asteroid Processing recipe of that mod is overwritten, making Promethium Powder inaccessible.

At some point I may make more of an effort to integrate the two mods' promethium recipes, but for the moment I just made a quick compatibility fix. You can now use the "promethium powder crushing" recipe to make promethium powder, which should solve this issue.

Thank you very much for addressing this issue so swiftly <3
I was luckily not yet at the point where it would've posed a problem, but I'm glad to have this sorted out.
