^^ Yup, that's a, uh, "feature" of my old-slash-actually-not-so-old movement code, with a side helping of low FPS Unity shenanigans. I've changed up the code recently, but not with that bug in mind, so there's a high chance it's still in there. I'll see to it.
^ Now this is new. Hang on while I see if I can reproduce it in E1.
e: puY, still in there. Fixing.
