The formations have been bugged since it was introduced in early access. It's been close to 10 months since it was introduced and it has still not been fixed 2 months after the game's official release. This is a basic CRPG mechanic that games in the 90s have properly working but this CRPG made in 2017 cannot have the same basic formation mechanic working? This should be higher on the priority list of bugs to fix.
