I see the problem with the templets, yes this was addressed last week that "the bakers replace the templets" because the old ones are possible defective.
At the end of the day any templet created using a defective templet will need to be replaced.
So more or less you need to replace any user templets with each update.
The question is.... What if a problem that someone keeps seeing is related to an old temple and not Sonar itself?
From the ground up if a templet is an issue... this needs to be addressed and fixed so moving forward user templets as well as the older templets are solid and bugless. A bugless templet should be a priority update...
I could be missing something so... lol
Peace!
