I got bitten by these problems too. It seems as if Jolla doesn't care about patchmanager and the patches. Nothing in the latest minor update suggested any problems with the patches I've applied, yet I couldn't even unlock my phone after installing, due to Maze lock being in a b0rked state. Would it help to lobby for a notification system which could warn patchmanager on the files being changed in an update? Or is such mechanism already available?
