@johnpollard I also noticed something strange. If I modify some code and repackage my Win64/Linux builds, their GUID changes. However, my Mac build seems to retain same GUID despite successive builds. I did a clean in XCode and deleted and regenerated a bunch of files, but it’s still quite unhappy with me. Let me know if there’s some more debugging I can help with! I’m very unfamiliar with GUID stuff but I think I am going to have to get to know it well.
