Hello again and thanks for your help last time, and hoping you guys can help me out this time too :)) So I bought two free AO and want to combine them but failed, so I decided to use both of them, and it works, but there a new problem. I don't like my both walking AOs, so I deleted it, change it back to original and its work. But maybe because of that that it isn't run very smoothly, always get stuck in standing position whenever I walk, unless I jump up, and even after that its come back to standing-walking thing again.
