It's really hard to explain, but it's like a game freeze without an actual freeze. It's a freeze of the last command or character input that freezes, then continuously repeats itself.

I'll try and provide an example: One time I was turning right and the game had a hiccup and I lost complete control of my character, he kept spinning in circles to the right as the game froze my last input, which was 'turning to the right'.

It often happens when I am running to places as well, sometimes the game hiccups and my character keeps running even though I am not moving/pressing anything on the controller (as it was the last thing I was doing). It usually happens for about 15-20 seconds for me. It's quite dire when it happens around combat or when I'm approaching the end of a cliff (lol). :/

Was just curious if anyone else has experienced the same issue.

Yes, I have experienced this issue before. Several times, infact. It would always happen while I was running or dashing. Even after I had let go of the control stick, my character would continues to run in one direction and moving the control stick afterwards wouldn't change their direction. It would stop after a while and I would regain control, but it was still really annoying. Especially in combat.

It happened a couple times when I was approaching the end of a cliff and I had to watch in complete terror as my character stylishly plumbeted probably 1,000ft+

Yeah happened to me too. A fair bit actually. I'd only stop running once I ran into a rock or something.

I had something similar to this happen to me but it wasn't exactly my character moving. Everything else around me was moving but I couldn't move my character at all (no my batteries were not dead). I could see a river flowing and the clouds moving but my character would just not move then I had to do a hard reset.
