If it was only one night then my guess is that the lane conditions were different (carry-down, etc.).
Any reactive ball will absorb oil. If you've got around 60 games on it then find a shop with a Revivor and have the oil extracted and a light resurface done.
Sorry, but the hot water method is better than nothing, but it doesn't get much out. We routinely have balls bleed oil for 4 hours and more in the Revivor. No one is going to keep the water warm enough, and change it frequently enough to do a thorough job.
We sell tons of Storm, and Roto Grip equipment here in Utah and their coverstocks respond very well to the above mentioned process. At worst case scenario your ball needs some maintenance, but I don't believe that it's dead for a second. Good luck.
