Southern Swamp isn't spawning a bonus subdungeon, while the Eastern Tundra is.
BIG ONE: Noticable slowdown in Cha'Dylan subdungeon. More often than not for the last 2-3 times, the game freezes for a short while when I hit Cha'Dylan - it migh be sprites from all the blinking snakes. Sometimes my cursor even develops a little "waiting" hourglass. It scared the hell out of me because it looked like it was about to crash.
And now the vampire chef spawned no red shrub at all. And it's in most of the recipies.
