Hey @kcee, welcome to the discourse, and awesome job using the bug report template on your first bug report! Two quick questions for you. 1) what version are you getting this error in, 2) can you upload your save folder where this is happening (post a link to a shared folder in dropbox, google drive, or a similar cloud service) so TR can take a look?
On a separate note, paging @8bitcrab, @Relyss, and @SteveAdamo: while the description is a little different, this seems very much like that other footman issue reported yesterday…with the strange movements and the running in place…
Edit: Here we go!
