And also just to clarify, the PODC update code might have been accidentally picking some of the bankroll outputs; so let's see if this problem is resolved in the next version.
I can say for sure the next version will not spend bankroll transaction outputs for 'exec bankroll' or podcupdates (as I did some testing last night with the new version).
I believe PrivateSend also makes .001 denomination and I remember podcupdate and PrivateSend could not be used in the same wallet. If you mixed coins, your podcupdate could combined all those mixed denominations together. I suppose if your fix works as intended, the side benefit is that PrivateSend is also excluded from podcupdate?
Those PS rounds are in thousands though, I think our podc update only excludes: locked, sanc locked, and pog bankroll denoms.
We would have to specifically test that PS issue and probably do another patch for that case.
