It seems that for some time now, Exophase has been unable to detect certain games on the GOG platform.
For example, the GOG achievements for the following games are missing:
SpongeBob Squarepants: Titans of the Tide
Strange Antiquities
Tattoo Tycoon
Twilight Oracle
Wreckreation
Ys vs. Trails in the Sky: Alternative Saga
And there are surely many others that I haven't noticed. If they have something in common, perhaps you can figure out why they aren't being detected, thanks.
