Stuck after attempting to grab survivor.
This has happened a few times before with locker grabs, but I was able to escape the "sticky floor glitch" by opening the locker.
I went to grab a Claudette off of a gen. The animation started but she let go before she could actually get grabbed, cancelling the grab. That's an issue on it's own, but, it doesn't help that, afterwards, I was stuck where I attempted the grab and could not move at all. If I tried to, I would immediately be sucked back to that spot. I pulled out my phone to record the issue, although I later accidentally deleted this video from YouTube.
This happened as The Shape, but it likely happens on other killers as well.
