Scripts

the mission is completed, but the video doesn't play.

I think it works like this: it first completes the mission and then plays the video. These things have a higher priority than scripts and are executed first. You need to make it so that the task doesn't complete the mission, play the video, wait a bit (using the sleep function), and then complete the mission using the script function Win() (I think it's with a capital letter, but I'm not sure, check me).
