We will release 0.8.4b
As 0.8.3b did not fix the issue for all users we will do a minor patch of 0.8.4b that should move the folders correctly to retrodeck/ES-DE/ and force set the correct path in ES_Config.
The 0.8.0b branch is still on the old manifest and it is a bit unwieldy to debug and we are making changes to our testing routines and the tester user program.
In some more positive news for @everyone. As soon as we got this fixed we will post our blogpost for August detailing some of the work we have done during the summertime (the new manifest).
