Playing through a standard Hard campaign, by the time I finished off the enemy in Old Fort Creek, I realized that all of the exit points had vanished off the map. I restarted RWR and reloaded the game. The exit points re-appeared on the map, but they don't work. I can stand on an exit point forever without triggering the exit. The campaign is effectively stuck. So far I'm only 1-for-3 being able to complete campaigns.

As you advised other posters, I will email in my savegame.

Mac OS X 10.9.5

This is a not so uncommon Mac specific issue and has been fixed for the next version (coming next week-end).
