I have what I'm assuming is a seized nipple and spoke on a Bonty wheel. This is a cyclocross wheel, so it's seen lots of muck and rain, and when I trued it, the (bladed) spoke kept turning with the nipple. I put a few extra drops of oil on it, tried to loosen it and retighten/true and still not great. Any recommendations as I'm expecting it to unwind at some point and cause a big wobble? Many thanks.
