Some jumping enemies aren't displaying the correct shadow.
1. As a Vire reaches its crest in its jump, a shadow appears very briefly about two tiles below it. View any Vire and you'll see this bug, but look hard. I tried to capture a screenshot of this, but it was impossible (I took, like, 30 screenshots and the glitch showed up in none).
2. A Pol's Voices's shadow doesn't even adjust to the Pol's Voice's height; that is, it acts as if the Pol's Voice doesn't even jump. This is very easy to spot.
3. Tektites are fine, so there's no need to inspect them.
Just to make DN happy, I spotted these bugs in my 2.10 quest (though it isn't necessary to replicate them). 😉
