If you have two playbacks running the same autoload and you release one of them, the autoload releases to. would be nice if there was a HTP option for autoloads so they remain if they are still running on a different playback
I think what you are actually asking for is that autoloads only get killed once the last cue list that loaded them kills them. At the moment the first cue list to kill them will kill the autoload. Its nothing to do with HTP?
