I was recently trying out a few things in 1.17 and thought I'd start with displaying an entitys Pos[] with armorstand names. The problem is that I can't get selector argument to work in JSON format anymore, only "name".
data merge block -11 31 5 {Text1:'{"score":{"objective":"x_pos","selector":"@p"}}'}
That does not work, whilst it used to, but this does
data merge block -11 31 5 {Text1:'{"score":{"name":"__Myth_","selector":"@p","objective":"x_pos"}}'}
Any ideas?
