How do I debug event group status?

You could put a Browser action 'Log' inside each group to output something to console only if the group is active.

Thanks, apart from that how can i display errors from the game?

I found that Audio still plays even my action select the wrong folder. ie, the audio file is in Music folder, but I selected Sound folder.

This causes inconsistent behaviour on different platforms.

I'd like to get some errors like "audio not found"
