My game simply won't launch... I press "Play", it takes maybe 5 seconds to start loading the green bar, but the green bar only ever gets about halfway through before it freezes. "Play" is greyed out and the game stays like this literally hours...
No crash report, the launcher doesn't even close.

A major issue related to this is that the launcher announces what it has finished but not what it's trying to do. (EDIT: at least with the resources)
Also, I'm not sure why they added this new "asset management system", specifically putting up-to-date assets in the "legacy" folder, and I don't get why all of the files also stay in the objects folder. It's now taking up 266 MB for both folders..... I might understand if this management system moved assets around as-needed, or even sym-linked the files so all of the different versions used the same set of assets (unless they have a different resolution or setup), but currently it is duplicating instead of de-duplicating. The ~/indexes/legacy.json files contains all of the hashes and file paths, so I don't think keeping them in the objects folder is necessary, as this file can allow you to do both operations, so move the files (or copy and delete the source file) instead of copying them.
Also, I'm sure this is going to confuse new pack makers with the /legacy/ folder, as they will try to use this in their pack structure somehow, despite the fact that isn't how it loads.
