A few more;
6) Using a ranged attack on Tamed Green Dragon, enemy did not attempt close the distance to hit with dragon breath by just one tile allowing me to kill it without taking a single hit.
7) At Cinder Keep an enemy spawned inside the walls there as well, couldn't find a way in so I assumed this was unintended.
8) Despite some of these inaccessible spawns, I'm now pretty certain I've run into the false positive red-tile enemy awareness indicators. Saw a few that happened within my field of view that were isolated, single blips with no NPCs in sight. It seemed the game would stutter a little when this occurred, maybe an issue with loading/unloading zones?
9)Equipping a two handed weapon in the shield slot allows you to switch it with a one handed weapon into the shield slot but not the other way around (2-hander to sword slot doesn't allow you to put a shield there) so it seems like one of these is unintentional. Doesn't break anything that I could tell.
10) Elven Wardancers consistently damage themselves with blade dance ability, which seems off.
Finally less an explicit bug and more corroborating some of the performance issues when having uncovered a large area of the map. Stuttering is not too bad on the main screen though I have messed up inconsequential moves a couple times as a result of it. The main thing is that the map slows to a crawl trying to pan it around. Moving to a different Z-level with little uncovered and it goes back to perfectly smooth.
