Weird Witcher 3 Bug - Unable to Save or Move

I was unable to save or move after completing the Possession quest. I tried reloading from an earlier checkpoint but it was still bugged after completing the quest. 

Enemy NPCs won't ignore me and I wasn't able to attack them. The only way I could get around but jumping and using WASD. 

The solution to fix the bug is to find a marker and move to a different map and meditate for several hours. You should be able to save and normally move now.
