No worries. I had no way of going down a rabbit hole for this without knowing how to recreate it.
I wonder if it's because I'm allowing keyboard inputs AND gamepad inputs at the same time. Like maybe if you had your mouse moving a little bit or something it might cause this. Not sure. I can at least try that in the future (and I need to have the game swap control types when it gets input from one or the other at some point anyways).
