Matinee not playing in Packaged Game

In one of my levels, there’s a matinee sequence that will play once the player has interacted with a trigger. For some reason the matinee will play in editor mode, but not when packaged. At first I thought this could be a blueprint logic error, but now I’m thinking there may be something wrong with the matinee system.

The game is currently being made with 4.16, and the matinee sequences were created back in an earlier version before sequencer was available. Does anyone know what could be causing this?

Is there a way to just convert matinee into sequencer?
