Ok, this is really pissing me off. I copied a working camera from one of my previous maps into a new one. The only thing I modified was the position of the path corners (I also removed a few extra ones, but I checked them for connection).
Anyways, camera doesn't want to activate. I'm sure I've checked everything, but it still doesn't work. To avoid detailing every entity, I'm just tossing it in the problem maps section.
