Nemesis Walking Glitch/Bug

So I just got another killer to level 50 (the Artist) and thought I'd get to work on Nemesis (who I only had at level 22). Got into my first game, loaded in at Ormond and chased a David King around for about a minute and tried getting out my Tentacle Strike but nothing happened (no animation, no text prompt, nothing).

As a result I resorted to just hitting him and then knocking him down with my basi cx attacks. I wanted to try and see if using my Tentacle Strike on him while he was down would leave him contaminated so I tried to use the Power again only this time, doing so reduced me to a walking pace as if I had the Tentacle out, but again, no animation. Luckily, I was close to a hook and had to plod my way over to it at this limited speed even adyer id picked him up.

Following my hanging him on the hook, I turned around only to find that my speed was reduced so much that I could barely move at all. I tried everything from attacking to using my Tentacle Strike and nothing helped. My Tentacle Strike had its text prompts back with the same delay as usual to account for the animation only there was no animation happening. My attacks worked fine but my lunge attack didnt take me forward at all, just left me in place. Even hitting another survivor who came close didn't help and I spent the entirety of thr remainded of the match, snail crawling my way across the bottom level of the main building to try and see if breaking a door might snap me put of it but I was moving so slow that the survivors finished all the generators and left before I could complete my 20 meter journey.

Has anyone else had anything like this before and if so, is there a way to fix it?? Is it unique to Nemesis?? Does something trigger it?? Finally, regardless of anything else, how can I notify devs about this?? I have videos but they are on my Xbox/Xbox Live profile so I don't know how to attach them or if they would attach at all since they are 2 and 5 minutes long respectively.
