I thought it might be a behavior, but I cannot find any where that field should be changed at the time the problem is occurring. Also, The fact that the problem is intermittent also makes me question if it is caused by a behavior. I would expect that a problem caused by a behavior running at the wrong time would at least run consistently at the wrong time, but this issue does not have any consistency.
I have tried running in debug mode, but it is very slow so it will take a while to complete meaningful testing in this manner.
We are running version 1.14
