Normally when you delete a Sound in studio that has the Looped value set to true, it doesn’t loop when you delete it when it’s being previewed. This isn’t true when you shift select it with another sound and delete it. It has to be being previewed as well. If PlayOnRemove is set to true it doesn’t loop. If you do it with more than 2 sounds with the same exact properties that are playing, all but first one will continue to be looped as well.
It’s very particular and insignificant, but an issue none the less.
