I've made several batches of different kinds of soap, and this is the only batch that has this issue. I made it using a goats milk soap base, brown liquid dye, and Fudge Brownie fragrance oil from Wholesale Supplies Plus (which I've since learned doesn't have very good fragrances...I ordered a strawberry from them as well and it had a horrible chemical smell to it). Anyways, the bars initially came out fine, so I wrapped them in tissue paper to store them like I do my other bars.
But one of my friends, who took one of the bars home with her, said her bar was starting to look sort of gross. I unwrapped one of mine and it looked like this:

Ew! It initially looked like gold glitter, but using the macro setting on my camera, I was able to see that it seemed to be tiny sweat droplets. I quickly checked all my other soaps, but only this batch with this particular fragrance did this. Can someone tell me what happened, and how I can avoid it next time? This was one of my first batches, so it's highly plausible that it was overheated during the melting process, but does that account for this?
