Asked a few friends today restarted steam and sandstorm and still they could not see me as playing it in steam
People can't see when I'm playing Sandstorm on Steam
Check to make sure you're signed to your friends. As in, make sure your Steam Profile appears in "Online" mode.
Yeah I cant say ive ever had this issue as long as the game is on steam. Non-steam games may sometimes have this issue. Like Price said as far as checking your friends list and making sure you’re signed in. If you’re logging into steam and your friends list isnt auto logging in you can change that in settings.
