TimewarpML v0.4.5 dev003 crashed during render! Can it be restarted or continued?

Has any been able to restart up a ML render that crashes or continue one? My shot is a 3:30 duration single clip, so exporting the exr source plate is quite time consuming (almost 2hrs). It failed about 15% into the processing of frames. The render may take a full day, so restarting is not an option.
