When will moonsine materials be available from the nuts vendor?

Wish they would increase the cap for Nuts. If the new stuff for upgrading the Causality gear requires Nuts as did the stuff for upgrading the Astronomy gear, it would be nice not having to waste Nuts on junk just to avoid going over cap.

Use the nuts to buy Moonward gear to level desynthesis (at 570, it's great for getting to the current 610 cap).

If your desynthesis is capped or you don't care about it, buy materia to store until 6.4. All that saved up materia I sold the first week of 6.2 was very profitable.

The cap is there to get you to use the currency instead of hoard it. If you genuinely think that nuts are only good for buying junk, then why care about them being capped when you can ignore them instead.
