I guess taking a couple day off from the problem helped. When the issue started I thought the fact that every time the file was reloaded it worked was strange. I realized why today.
The issue is in how I was defining my "placeholder" properties. From the documentation I was, incorrectly, under the impression that any model members beginning with an underscore (_) were treated similar to the other members -- i.e. they are initialized for every instance. This is NOT the case. The _members list was growing, until the model was freshly reloaded into memory. I had printed the _members list, BUT I just had not run through enough combinations with it printing to see the issue happen.
