I had finished off what I thought were the last two Tequatl achievements tonight, ‘Tail Flail’ and ‘I Found It!’, only to find that the ‘Above the Waves’ achievement that I had gotten yesterday had been reset, so I’m not done after all. It’s not a big deal; I can redo it. It’s just weird that it reset itself like that.
Also, the Dry Top lost coins appear to have reset as well for me. The count in the achievement panel is still accurate, but I’m finding coins that I know I already found, and which should therefore not be visible to me. These coins also don’t have any flash/discovery animation when clicked on; they just disappear.
