Bugs - stairs, shift to sprint, disappearing dandelion tufts

[jadefishes]

Bugs I've encountered in the first couple of hours of play. Other than the disappearing dandelion, I've seen/experienced them repeatedly.  

1. There's something that causes a stop on the next to last step of grass stairs (ascending). I have to jump that last stair to get up. This happens every time, whether there's a floor attached to the stairs or not. 
2. Intermittently when I hold shift to sprint, I instead sprint backwards. It happens often when jumping or ascending rocky terrain while sprinting. 
3. All dandelion tufts and stems just disappeared once the dandelion was chopped down.
4. Sometimes I can't sort my inventory or container even when they're selected. 

I've also seen things like bees frozen in the sky and I don't know if you meant for aphids to be common underground, but I've found them in pretty much every tunnel I've explored outside of the orientation area.
