One thing I did notice, but isn't exactly a bug or anything, just maybe unintentional, is that you can jump to cancel doing a short climb during the time the character is rotating to face the wall to climb. It can also be interrupted during the animation to bring their hands up to the wall but you only have a small window of opportunity to do it. Once he starts climbing, you can't stop it.
This did not cause any glitches though, no getting stuck, no clipping through walls, the character was completely normal after canceling it. I just wonder if the player *should* be able to cancel it? It's a bit jarring I guess. Not something major though.
