the Twitch launcher is showing 099 as the latest version of Grail, same goes for Wholly (its stuck at 070)

Have had to manually download 100 and 101

I did not realize this. Thanks for the warning. Now I have to figure out why this has not been updated properly.

For the latest release I only marked the Retail version and that seems to have made it so Twitch displays the version. I do not know whether Twitch can be made to show only Classic or a combination of Classic and Retail. But at least it is showing the latest version.
