Remove Weirdness Isolation from sidebar

Simple enough, I assume. Fast Eddie cut the useless index of Weirdness Isolation Tropes a while ago, but it's still on the sidebar under "Other Categories." I doubt many people actually click on it, but if anyone does they could be left scratching their head. Thanks for the help!

Bump. This seems so simple that I probably should've just PM'ed Fast Eddie.

I PM'ed Fast Eddie, he removed it. Requesting a lock for this thread.
