I want to reiterate how much I'm enjoying this game.
In this update, the use of the 'gang' button to deselect all had become finicky. I found that it wouldn't allow me to unpick everyone if everyone were selected, or if some were deselected, but *would* let me use the gang button to deselect everyone if specific seemingly random combinations of members were pre-deselected. I'll try to find some unifying theme in which need to be inactive/active to allow it.

Above : Deselect available after stumbling on 'magic' combination.

Deselect not available, despite all mercs being active.

Most combinations of active/inactive mercs leave the gang button in Select All mode, as anticipated.
