Hello David,
Thank you for your question about this snipe. I checked the log, and noticed that the snipe was actually added precisely at the ending time of the auction:
1. Snipe was added at 19:29:23
2. Snipe ended at 19:29:23.
3. We tried to schedule snipe at 19:31:01.
Normally, the system won't let you add the snipe. There was supposed to be an error message. I'll check into this right away and hopefully can release a patch so that you don't encounter this again.
If you still need additional assistance or have other questions, please feel free to reply and we can take the next step. Thank you for taking the time to write in.
