[1.3 I think][Other] I lost my skins

I was on the plane,and tried to play Primal Carnage without wifi. I was able to get onto it and play some of it but I noticed that my skins were gone. I thought that this was because I didn't have wifi and thought nothing of it, but now when I have wifi and got onto the game, my skins were still gone, but they do appear in my steam inventory. Please help me with this, because I have used money to pay for this. I'm not sure if this is do to my present wifi connection though because my store didn't have anything in it either but I'm really not sure. Thank You,
