Nasty bug when trying to create a preplanned defense

[Hawkeye]

This happens when you prepare your mercs and set overwatch zones when a hostile force is heading towards your sector. As soon as the hostiles enter your sector the game goes into default setup mode and ignores the positions you prepared.

Once the baddies reach the line of contact, your mercs are magically transported to the original setup locations. Which are now behind the hostile squad. This makes it impossible to ambush them at the sector entrance.

This is with a clean installation. Running no mods or any edits on my side. There needs to be a better solution for this. For example allowing us to add a setup zone in a sector, either by paying cash or using materials.
