Thanks @Negreb for writing in again 
I replied with a temporary fix until the Stack update could be released but have pushed that out today:
You’ve just been sent email updates about this and also can update from within RapidWeaver 7 or 8.
Let me just take a moment to thank @isaiah for his thorough and very detailed answer over the weekend especially. But also as it was super helpful, unassuming and supportive.
High Five!
