I think I accidentally reversed a couple cogs on my cassette when I replaced my rear wheel over the weekend on my commuter bike. By the time I can get home to fix it, it'll be around 20-21 miles ridden. 10-11 miles of it ridden without me realizing what I did wrong (and trying to use those cogs). I'm hoping I didn't ruin the cogs that were reversed... anyone know if I may have rounded out the teeth and/or chain with my screw up given the miles ridden? I feel like an dunce. When using the reversed cogs/sprockets, the derailleur wanted to shift to the harder gear (or maybe the other way around, don't remember).
