Leet Sketcher's Anniversary Pack

For some reason the game didn't recognize locke as a party member during the event... was anything else done before this that the game wouldn't consider normal? Like sequence breaking or anything? I know if you have an "invisible" character the game wont register collisions with non-traversable squares, which would explain getting out of bounds. It's just a matter of figuring out why the game didn't register Locke or your PC sprite.
