Alright, sounds good! 
The bug you are referring to is when the download is complete, something goes wrong during the “Mounting” part of the process, where it installs and verifies the files into your application.
It’s not something I can control (It’s using the AssetRegistry module), but when it happens you’ve already finished downloading all files so an easy solution is to retrigger the AssetPack install node and it will skip directly to the mounting part and it will retry mounting all the PAKs.
For those rare occasions were it happens, it works the second time around everytime in my experience.
Anyhow, keep an eye out for the update! I hope it will make the product even more streamlined and easy to understand. An update to the PDF documentation will happen at the same time!
