Just finished the EA content and have to say how much I loved it. I didnt't even really encounter that many bugs during it and had a very solid game experience. Can't wait for more!
Anyway, the one bug I did encounter was when trying to use the goodberries from my ranger. The buttons between eating the berries yourself and giving them to another companion were swapped around, where "eat" would allow you to select a companion and "feed to" (or whatever the correct menu option is) allows you to eat them yourself. Just wanted to highlight that as it took me a while to figure out what was going on.
