Forum:Favor points disappearing

Hi..I have been playing Castle Age for awhile now. I had 182 favor points and got Slayers embrace and blood vestment as well as Suri's Windthorn Wand, Sunstone Crest, and Gilded Tiara. Each of Suri's things are 25 favor points a piece. Both of Slayer's items are 25 a piece also. 25 times 3 (for Suri's items) = 75 and 2 times 25 (Slayers items)=50. 75 plus 50 favor points is 125. 182 (original favor points) minus 125 (total amount i spent) equals 57..So what happened to 50 favor points i had???
