Must download new map and gamemode!
The original file got corrupted by the extremely reliable and bug free Halo 5 updates, I kept waiting to see if the issue would self resolve, sadly it did not, this has happened to a few of our maps (This issue un-fixable by the way) but we decided to fix this one map because it was one of our favorites to play. Despite this giant inconvenience it was fun to create everything on this map excluding scripts.
