Just got around to trying the latest version of TE4 with the animation changes and such, and I've noticed a bug with using a controller.
To be specific, if you turn on "Use Alternate Strike Up/Down", the player controlled character will constantly run forward, or in rare cases backwards, without any input from me. If you turn that option off, the effect goes away. I've tried two different controllers: an Xbox One controller and a PS2 controller hooked up to my computer via an adapter, and the same problem occurs with both.
Could you look into it and see if its a bug on TE's end, as I can't imagine its two controllers both having a problem?
