I'm having a problem building my map. It crawls to about 3% completed then races to 99.98% and just stops. The maps continue to processes but it doesn't continue building. I've tried upgrading to May, removing vertex painting, and even removing all my volumes and fog. Nothing seems to fix it. Here is my log.
