I had it mostly complete and thought I'd try another ugly hack idea to get it to render the initial portraits without a manual scroll, and it seems to work. As mentioned in it, need new version of the random portraits mod, or might work if this mod is after the random portraits mod in the order, haven't tested that. It still takes a while to load a large list, but we're talking like 5-10 seconds on a good computer, instead of like 1-5 minutes or crashing before.
