There's a nasty crash bug that seems to randomly happen during combat. I've tried to isolate and fix it and hope this update does the job. However to get a better handle on it in the future I've added a debug log to the pause menu so when you've got some errors popping up you can send a screenshot of the log. That should help me fix bugs like that in the future. 

I've also used the chance to fix some other minor issues:

• Bugfix: Elite Crusader now properly stuns enemies
• Bugfix: Warden of the engine buffs as designed
• Balancing: Higher chance for rare+ rewards in events
• Balancing: Higher chance for rare+ followers in recruiting
• Balancing: Enemy surrender chance adjusted for difficulty
• Balancing: Adding visualization of valuable (trash & luxury) rarity
• Feature: Added debug log to pause menu on crash.
