i had a quick look through the source but I couldn't find where it would be defined that agglomerations couldn't be combined. btw sorry for asking a question about such an old version

it might be this but honestly im not that used to editing java code

The agglomeration itself doesn't really care about what's part of it as evidenced by the exploit that used to allow you to combine agglomerations. What I think you're looking for is the AgglomerateRecipe, more specifically the lines that check whether an item is a valid one to agglomerate.

ok thank you, i'll check it out and try to make it work when i get home

ik im a bit late but when i try to compile the mod it throws an error
