I was wondering if there's anyway to exit combat without needing to 'flee' to whatever WP it sends me to.

Many times on my stealth rogue character, I've been locked into combat and stuck waiting for turns to cycle through while I'm flanking around and a good 4-5 turns away from the enemy. Especially while I'm out of sight of every known enemy currently in combat. It's a little annoying that I can't just exit out and re-enter sneak to sneak around and flank those undead in the smoke screen.

This was by far my favorite thing to do in the Fallout 1&2 games(blind and flank), for if you don't know, utilize the same AP based combat style.
