I'm not sure exactly what happened, but somehow I played through quests in a way that glitched my game from working correctly when I found the temple - where the you fight Garcia.
When I got to that temple, nothing happened. I double and triple checked NPCs all over the game world and tried various suggestions from other people on the internet without success.
I ended up losing about 10 hours and restoring to a save game where I first meet Garcia in the tribal camp. I then proceeded very carefully through the quests and everything worked just fine. I finished Risen 2 a few days ago and I very much enjoyed the game.
