Activated Addresable on an asset and got scary dialog box/progress bar thingy

Installed Addressable system and then I went to an asset and clicked the Addressable option. This is what I got and now the editor appears frozen. I'm not sure if the progress bar is advancing or not so I'm going to leave it overnight.

Regardless of if it is doing anything or not it is a rather scary looking dialog and doesn't communicate anything to the user.

 

The editor after a while just crashed (CTD no report window or anything) and now after restarting it things seem to be working.

 

Thanks for letting us know. It would seem Unity couldn't create the core asset we need. Without more details, it's hard to know why that happened, so if others see this same behavior (or if you see it again), please let us know.

Thanks for trying out Addressables,
Bill
