Both use the modid "aeadditions". Aether Additions is a dead mod but this is still active, would you mind publishing this mod under a different modid? I know that can be world breaking but maybe add a conversion method in the mod. IDK but the mods are incompatible at the current state

I could probably change it to ae2additions and just convert aeadditions items to it. Lemme ponder this and work on a solution
