Poppy Wall collision bug
When I was Miss Fortune playing against a Poppy support I got stuck in a wall when Poppy charged me into it. I was stunned like normal but then I continued to not be able to move while it appeared my character model was stuck in the wall, stuttering left and right rapidly, and slowly sliding out of the wall. This is where I was finally able to move after many seconds and then inevitably dying to the opposing enemy team.
I don't know how many other people had seen this bug but it is literally game changing as I was inside a while for over 5 seconds.
