Trading window was open and my Barb snorred and spitted repeatedly on the ground not stopping it.
I CALL THAT BAD MANNERS in front of an honest Miner and Trader.
This is no hoax, it happened.
So if that is intended, then you could add a pool of spit to add some realism or just tell the Barb to stop that. Even this is considered bad manners and deadly insult under the barbarian tribesmen.
A funny bug, but purely cosmetic one. And i am not sure if this was lag related.
