If I shift just one cog up, the chain becomes tight again and works pretty normally. It's only that one combo, every other combo works, even the big/big cross chaining works. It's very confusing, I could possibly take a video if you want me to.
A video might help, but you're own eyes confirming whether the top loop sags when the wheel spins forward (coasting). This is pretty definitive, but note that I'm not taking about the cassette, but oiling the freehub ratchet or the seals between the freehub and hub.
BTW- some hubs and freehuns are very easily user serviced, others less so. Try searching for
lubricate (brand/model) freehub and see what's involved for your specific model.
