I'll take a look at this tonight. I've made a few changes to how the optimization works that may have had some unintended consequences. Blends behaving like exact stop mode sounds like what would happen if the optimization was aborted early. With any luck it will be a simple fix, since I haven't changed all that much in the last few weeks.
