I've died twice during the Search the Thief Camp mission... right at the end, only to have it reset me back to the middle of the Defeat the Thief Leader mission, yet all the soldiers from the latter mission are STILL running around...

This has happened both times.

Also during this mission, after the boss beats up Christof, during the battle with all the soldiers that storm the compound, Christof is labeled as Desert Raider, and he never gets back up. This is the battle that kills me every time.

We are aware of some issues with the mission Search the Thief Camp and are prioritizing fixes for them. Please keep an eye on the Bug Report Thread for updates to the issues.
