I tested this last night and it caused my game to crash.
Move to next map - Change to another map. This allows a campaign map structure to be built. - I think this is where you do the change level thing.
Move to next map - this is what might be causing the crash but I have no idea how this entity works at all. I have my map names as map1, map2, map3. For this option I first tried move to next map - map2, then map2.bsp, then maps/map2, then maps/map2.bsp.
I'm using a capture area to cap the flag when the flag caps it triggers this entity. The delay I have is set to 2 secs and at 2 secs dod crashes.
Anyone want to give it a try and see if they can get it to work?
