I doubt it crossed their mind that they were preventing players from completing a distinct quest when they changed it. Hopefully once it's been brought to their attention, they'll fix it so that this isn't the case. That said, I don't really like your chances of being able to complete the quest without waiting a year, but you never know.
As for completing the prayer achievement after already receiving the sled, I assume it will still give you a second one.
Thanks for the info, though I doubt my chances are good either way since I now completed the repeatable version this year. Will probably mess everything up either way. I wouldn't mind waiting a year if it was confirmed to be fixed to next year. I'm not really in a hurry
