Turret targeting error

Summary:
If an enemy targeted by a turret moves into cover from that turret, the turret doesn’t target other enemies.

Steps to reproduce:

  1. Let a group of enemies walk into the range of a turret.
  2. Wait for the turret to attack one enemy of the group.
  3. Lure the enemy behind cover with a footman or other hearthling so that the turret can’t attack it.

Expected Results:
The turret should switch targets and attack another enemy of the group.

Actual Results:
The turret sits there idling with enemies in range waiting for the initial target to come out.

Notes:
I had this error using the higher level turret (not the turnip shooter). Off course the easy workaround was to move my knight just from behind the cover to lure the enemy back into range of the turret, but I still think this should be fixed.
