I used the radial dial to access the "walk mode" feat under additional actions. After that, I logged out, reset my entire game including steam because I was experiencing missing body parts on some clothing items and that usually fixes it for me. After that I went about my business for a while and noticed I was still in walk mode. I tried to exit and was told i could not while in detect mode. I checked, I was not in detect mode. I tried again. I switched detect mode on and off and tried again. I attacked something and tried again. I cannot exit walk mode.
I fixed this at last by typing @walk. I am not sure if this is known to be broken and the @command is a hot fix or not, but it was very frustrating, especially if I were new and stumbled on it, not knowing how to fix it. Even though I solved the problem I figured I should still make a bug report.
Recreate: Use the Radial Dial by right clicking on yourself to access special abilities, more special abilities, additional actions, walk mode.
