That is likely the same fix I figured out last night. He agrees it should resolve the problem. I hope when he finishes work (a few hours from now) he will be able to perform the update and sort everything out.
I think it doesn't fix snapshots that were taken when the behavior was wrong (so between the time of the update and now). But snapshots from before the update should work now. Kinda annoying to find it out now, I have to check whether it could have been prevented somehow.
