After Beta ring update on 6/30 many of my games lost the picture for their game tile.

Incorrect. It will update the game to the equivalent of Beta 1.7.3 release. There have been many many many updates since then on the PC. After the 1.7.3. patch, they will work on updating the game to the equivalent of Beta 1.8 (the Adventure Update).
No word on timing on the Beta 1.8 update, although the developer has noted that, given the amount of changes to the game in Beta 1.8, it is much more challenging than Beta 1.7.3. After that, they will just ahead and patch the game to the current version
(so the scuttlebut goes).

Lost my stats after the Alpha.

Lost my stats after the Beta.

Looking forward to the full and final release of this baby, for MANY reasons.

First off, here op here is a tissue.

Secondly we need more beta testers or get rid of the tester we got now and get some more as half the time when the new update gets released to the general public there are still faults and bugs. Lost count of how many times i have had to reset my one because
of no picture on my screen but sound, or my games go to load then don't or other bugs that were not present before the update.

Thirdly you don't need to be in the dashboard beta to play Elite, Elite is an early access game so is open to everyone.

I don't think the games are lost for good, just that the app can't find them. My live tile is still updating the number of games where it's my turn.

I kind of have the same problem. I was trying to make an Achievements my background. The game tile showed that I had Achievements but when I opened it showed that I didn't have any. I have at least one Achievement per game that I
have. I'm in the Beta ring.
