You have built a new fabricator after installing the mod correct? I always forgot that and was like wtf I know I did it right!
When I did this previously I had to also add the primalitemstructure as a “for class” or it would not show up in my fabricator in mp. Storagebox worked for SP but had to have structure to see it MP.

For this would you then add both classes or will one class primal work for both i am haven this same issue my first mod i used just Storagebox and it seems to work in both sp and mp. now another mod using same layout will not show up in game but all works fine in dev kit
