Been playing the game a lot and a few bugs have cropped up.
1) The Gauntlets of the Underdog (or something to that effect) are medium gauntlets that give you advantage on attack rolls if you are surrounded by two or more people. That's great, but it doesn't let you sneak attack even though you have advantage (Yes, my rogue has mediaum armor proficiency.)
2) Eyebite can put my Elf to sleep, even though they are supposed to be immune to sleep.
3) I think the game may cheat when it comes to making concentration checks. I've seen enemies routinely succeeding on concentration checks when daking 40+ damage, which, while not impossible, is extremely hard.
