I just want to clear up some confusion regarding fabric api. I've seen some posts around but they don't seem exactly clear. So to run sodium, lithium, and phosphorus you need the fabric launcher. So to make a run allowed we just have to make sure the "fabric-api-0.30.3+1.16" isn't in our mods folder? Sorry if this is redundant jus trying to be clear as possible.

Yes that’s true just don’t have any version of fabric api in mods folder
