We refreshed the dremio cluster and logged in and found all of the reflections had been removed by dremio. Here is a profile for an example query that $dremio triggered to remove a reflection. Do you have any idea why this happened? This is in spite of Never Expire being set on the Source.

Also I noticed on a seperate occasion that the source Reflection settings had been updated without anyone doing so. Is it possible some of these settings are cached locally so rolling the cluster would clear them out?
