I renamed Gears to Gear, and, as usual, followed the "What links here" to update any last references. It listed pretty much every BC page, as expected, because BC-Nav's template pasted in the link. So I updated Template:BC-nav, and confirmed that some of the BC pages now properly link to Gear instead of Gears. However, after seeing "What links here", it's still saying they all point to Gears.
I thought it might be a cache thing, so I went to nocache version, and the issue was still there.
Anywho, just dropping this here in case we want to get a second pair of eyes on it to make sure it all carries over correctly. Let me know if I did anything wrong or missed something.
