That is indeed odd. You're using the latest version, correct?
At the very least, your stats should have changed back to what they were once the potion ran out.
That's what i would have thought. Instead, those stats seemed to be locked in (for that run) as my regular stats. Even a different transformation later with the featherweight potion changed my stats as normal to that form's stats but returned to wild form's stats after that. It seemed to be the specific combination of transformation and shredding trap that caused the problem.
It should be the latest version, as i bought the game only a few days ago.
