I’ve just lost potentially hours of work because I accidentally forgot a something in one of my loops and heres why…
When I pressed play in my studio, it locked up, and froze because I forgot something in a script, next thing you know you get the message saying “a script is hanging, would you like to kill it?”, I proceed by pressing yes, and instead of stopping the game, the game continues and now I cant actually stop testing the game, no buttons, no hotkeys, nothing.
It’s done this twice and its by far the most annoying thing I’ve experienced. 
If I press publish it publishes with the workspace in its active state with the dancefloor on and everything.
