I have finished the Christmas quest and wanted to warn you about the building of the ice castle. Once you construct this building you can no longer get anything from any of the sleigh flights but you need liquid nitrogen, freezer, 2 snow makers and artificial ice to complete it. These cost 8 green notes each so make sure you have them before you construct this building otherwise you will have to buy them like I did or just not build it. I have logged a complaint to GI.
