Your resources get updated periodically when you load windower, so it's overwritten what you changed in the resources, you'll have to find it again and rename it back to Cizin Breeches.
No, they won't be updated every time, only if they changed since the last time (an MD5 hash is saved locally to compare every time you log in). If you manually change them they won't update until someone updates the ones on the server. That said, they
were updated on the server a few days ago. But since Radec left we didn't have someone to give us new resources (we're working on our own resource extractor now), so the Cizin thing was updated manually. It's very possible it was misspelled somehow. Can someone check if it's spelled correctly in the resources? It could be that capitalization is also relevant (although to my knowledge it shouldn't be). If anyone can find a mistake let me know please, I'll try to fix it right away.
