Stealth is always uncertain if it cant verify the game.
The problem is its a new wave that has not been uploaded to ABGX database yet.
The ISO may well be safe to burn but because it cant pass basic stealth checks there is no way to be sure.
The way to know this for future games from imars is to check to see if ABGX does anything (in the way of changing it or patching it)when it verifies the new wave.

So if ABGX does nothing to change the ISO when it verifies the new wave then the burn would have always been safe.

But if ABGX does patch the new wave and change the ISO then we will always have to wait before burning.

Complex but very simple when you get your head round it!
