Cause currently when you start level it doesnt exactly reset the level but waits for the enemies to respawn
That explains why I saw the dragoons marching into town that one time.
Sometimes the dead bodies don't de-spawn from my previous play-through, and the level is basically empty without enemies aside from the occasional dead body that was left previously
Here's what I did during my playthrough:
>Play through the game for the first time normally, and Finish the level near the big statue
> Spawn back in town
> Go to Bounty dragoon and talk to him immediately (barely 3 seconds)
> click on "Empty Wanted Poster" empty as in, there's no-one inside the "Wanted" square
> click on the Check-mark when the wanted poster with the dragoon in it appears
> Spawn back in the level, but it's empty and still has the dead bodies from my last rampage
Hope this helps!
