In my hunt for explanations over things that I've been experiencing in Baldur's Gate 3 on Stadia since Patch #3 dropped, I just happened upon this article from October 6, 2020 which in a nutshell is what I have been dealing with:

The reviewer covers the basics over what I've been seeing since the patch in character creation, but I did not have any of this going on prior to the third patch dropping? Character creation worked like a charm and yes, I do use a Stadia controller. Whatever glitched for me since patch 3 arrived sounds exactly like what this writer described back in October.
I hope that some dev reads this and manages to route this to someone, at the moment recreating characters that I lost on Stadia due to the save erasures is not possible, since I can't select many of the attributes that I prefer for any characters. I am being forced to live with some things as a default setting, hair style, hair and eye color, etc.
