Yeah, I just tried it (even made a commit), however that broke the thing. The EntityInfoComponent from which I can extract the prefab for creating an item is in "internal" package and I cannot access it from within the mod. So, either we make it "public", leave the code in PojoEntityManager, or extract it in the event itself. For the time being it is not going to be a problem, as I will have to create my own items anyway, instead of re-using the Core items.
