I can debug more and see if that synchronization is happening. After testing today it seems maybe my hunch wasn't the root cause. If you disagree and I'm missing something, say so. I will take a look at that though--my hunch--to see if the thing I thought could be causing a problem can actually occur. If so, I'll figure out a fix. -Alex
