It's been that way since I can remember. If the group is placed on the 
current card, you can refer to it as "group", otherwise you need to use 
"background". This applies even to closed stacks, so maybe when it 
worked for you before, the current card of the stack happened to have 
the group on it.

This is an invalid reference:

put exists(background id 1004 of background id 1111 of card id 1016 of
stack "nv")

Since every group has a unique ID, you don't need to specify the 
enclosing group, only the specific background:

put exists(bg id 1004)
