Saw this happening several times as well. I ended up catching it on my stream earlier today.
Video of some warping seen over the course of two fights.
The warping when the puma was fleeing is somewhat questionable since I was in first person, all I know is that it disappeared on me and when I turned around, it seemed a little farther away than I thought it should be. In the very beginning it's definitely doing some crazy stuff. I was trying to hit it with a shuriken and nothing was happening.
No bash, can't test that.
