This morning, I went in to train my pet on health. Level 400, Health at 998 (2.5x cap at 1000)

I clicked on train, but oops, I didn't have enough funds. (my bad) Retrieve more sp from my vault and go back to training page -- my pet is now sitting with 1000 in health, as if I had indeed purchased a session, and then waited the 3.75 hours.

So... That doesn't seem like it should happen.

[edit] And on a somewhat related note - viewing my pet should have given me another tier of the "Lots of Health" achievement, but no go. Not sure if that is a glitch in the achievement tracking system, or a glitch due to whatever just happened with my pet. ... Actually, viewing it says that I'm still sitting on 980/1000, so, I think the achievement is just not tracking.

I've fallen behind on my pet training, but I haven't had it happen since. I just recreated the scenario, and my pet didn't glitch in the stats. So, it looks like it's resolved.

As for the achievements- those appear to be fine. The achievement revamp went through since I made the original post.
