I just tried to load a custom map "Coruscant_Heights" from single player gameplay and when i do, the game drops out to the main menu with a dialog box saying:
Error: 1. Missing Sound Sets!
This is the only custom map that this has happened too. It also throws this error if i run the map through multiplayer so it's definitly not a single-player map calling problem or anything.
If you need me to post up any system info or other custom pk3's i have give us ahoy.
All help greatly appreciated!
Anyone got any ideas?
