It is not possible to obtain the Luna aspect with silver. It is only available in silver bewitchment. But the mod / plugin replaces it with silver from thermal expansion
Hello Moettke, I tested this a bit and ended up making a bug report to the pack devs. Changes to fix it need to be made on both client and server so they need to make adjustments in the pack. However, I did find a workaround. The Mekanism Oredictionificator can swap Thermal ingots/blocks for Bewitchment ones. There may be other blocks in the pack capable of oredict swapping too. So you shouldn't have any trouble getting the ingots you need for now. Hopefully it's fixed in the next update and we won't need this extra step anymore. HanoverFist69
