I made a batch of lavender cp soap yesterday morning. All milk as liquid same ingredients I always use. I've made this recipe many many times before. I cut it up this afernoon and there were dark almost a rusty brown spot in a couple of the bars, also they were a little weepy looking. I know it's not dos. I'm wondering if the hot weather had something to do with it? Anyone ever have this happen? Is it oil that hasn't saponified? Appreciate any help in this mystery/
