Added a video input, added OnTransitionIn triggers, and added OnTransitionOut triggers. The transition out triggers are working, the transition in triggers are not. In this case an example is SetVolumeFade, fade out the targeted input on transition out, but does not fade the target volume up on transition in.

EDIT - Restart vMix did not help, restart PC fixed it, but after a moment it stopped working again. Basically it works the first time I do it, then after I transition out, and back in it stops working

Sent this show file to my coworker and he has the same issue. I will test with a blank show file soon

Not sure how, but I fixed it. The only thing different is a shorter delay on the OnTransitionIn of 5 instead of 100ms
