I bought steam punk joints and I can only see t hem via replay, Any solution?

It's how it is supposed to work since otherwise it would be difficult to use them effectively while you are playing.

So there is no way to see them ingame and is just a waste of money?

maybe the effect is set to "Only On Replays". try the to set it to "always on"

Change effects to ‘default’ , /dl and /lp yourself then do /opt obj 1

They were replay only a while back, I’m not sure if that is still the case. I believe it’s possible to see your opponents joints but not your own, for the sake of playability.
