Snowmen not resetting
Same.
Just go to that area with another character and you’ll be able to do the snowmen again.
Or build Snowmen in other cities? Out in the World Maps?
Good luck.
It’s a common misconception that the Snowmen reset daily. In fact, each Magic Snow pile can only be used ONCE per character, but this limit is per map instance. So if my Warrior had gone to DR Instance #1 and used all the Magic Snow, if he logged back in the next day to Instance #1, they would still all be activated. However, if he logged back into DR Instance #2, all the Magic Snow would register as being unused.
Because DR instances have such a high turnover due to a flood of players coming in for the dailies, then leaving again, chances are you’ll always log back into a new instance, hence the perception that the Snowmen reset daily.
As Inculpatus mentioned, you can also build Snowmen in the other capital cities and out in the World Maps.
