Some things I've noticed so far

Khargoth

1. While I was in multiplayer, when Imeon was just about to talk to me, she would spam out a lot of conversation in the chat box.

2. When looking at the record for any dual/multi class, instead of saying:
Fighter level X
XXXXXX

Thief level X
XXXXXX

It will say:

Fighter/Thief Level X
XXXXXX

Fighter/Thief Level X
XXXXXX

I'm not sure if this is a bug, but it should be changed imo.

3. When resting in multiplayer, healing spells are not cast on rest.

If I notice anything else, I'll let you guys know. Thanks

4. After beating the game the first time, I've really taken a liking to having Boots of the Cheater(Cheetah) from the start. I've noticed a lot of sequences/triggers haven't been activated due to this, such as the goblins spawning in Jon Irenicus' Dungeon, or a quest to get Hexxat.

5. While going into a dream where my party gets knocked down, all the characters talk simultaneously.

6. When I was walking around Waukeen's Promenade, Hareishan was able to talk to me while I was in a shop and she was on the other side of the map.

7. I've noticed NPCs initiating dialogue all at once, like 3 party members talking to me right after another, where as in the original it was spaced out

(Just as a suggestion -- if you are finding good bugs, I reckon it helps the devs from a paperwork perspective if they are listed in separate posts.)
