Both bismuth and manganese fail to add their ores to SE scrap recycling. The internal name for the recipe is “se-scrap-hard-recycling”, but your mods use “se-scrap-recycling”, so the changes don’t go through.

With SE + K2, the recipes for ores from matter follow a rule: Making off-planet ores uses matter stabilizers, and making all other resources uses basic matter stabilizers. Your mods seem to not do this correctly. Manganese ore is made with no stabilizer, and bismuth ore is made with a regular stabilizer instead of a basic one.

Also in SEK2, matter fusion and matter liberation use 10x smaller amounts of particle stream than they’re supposed to. Adding K2 to SE makes matter fusion cost 500 particle stream instead of 50, and the SEK2 exclusive matter liberation recipes are supposed to input 500 particle stream and output 600, but for bismuth and manganese they currently input 50 and output 60.
