In this changeset, you deleted a piste way called Cowpuncher. You won't be able to see it now because of that.
That's great to hear that you work here, I'm sure you have some really valuable map info for the area! For map updates, it depends. If you mean the openstreetmap.org "standard" map, it's usually pretty quick, like 5 mins max. (You might need to clear your browser's cache, ie ctrl+f5, to get the updated tiles.)
If you're looking at other maps that use OSM data, it can vary wildly depending on their systems. Anywhere from hours to months.
