Okay, hold on a minute, which recipe is this? You mention one traced quickly is this the recipe when you used HO Sunflower oil. I will mention neither HO Sunflower Oil or OO will trace quickly and 26% Palm is really not high enough to create a false trace at 100ºF. Is there any added fragrance that could have caused this to overheat and separate? Did you insulate it? It looks more like overheating and separating to me, not false tracing.
I really do not know what everyone is looking at that would be a false trace. Unless this is the batch she mentioned thickened up quickly. I deal with a false trace in all my palm batches because I soap cool with a 40% palm content, I just wait until it warms up then continue on. The batch which she mentioned thickened up quickly could have been a false trace but it is unclear to me which batch this is.
As Lsg mentioned put it in a crock pot and cook it until it comes together.
