I can't find anywhere that this is intended behavior, so reporting in case this is unintended.

So, if the Knight drops a guard on low ground, but the guard can 'see' a survivor on an upper level, the guard will just take to the air and fly in a direct path to the survivor. I can see them dropping down if the survivor is on the lower level being intended, but having them fly upward directly toward the survivor seems like a pathing bug.

To reproduce:

1. Have knight in the lower level of an area, with a survivor above.

2. Make sure you can visibly see the survivor from below. Known locations for this working are if the survivor is near a drop down, or vault location.

3. Have the knight place a patrol guard on the low ground near the drop down. Make sure the patrol circle crosses below the survivor at some point in the path (so the survivor is in the 'cylinder').

4. The patrol will agro on the survivor (likely correct), but then fly in a direct path to the upper level to chase/attack (possible bug).

Additional info: confirmed that this behavior functions in areas like:

* Disturbed Ward main building. Survivor upstairs near the floor hole by main building generator, knight/guard below by lockers.

* Midwich Elementary exit gate with the vault. Survivor upstairs in the jump scare locker room by the wall drop down, knight/guard downstairs at the exit gate.

* Dead Dawg Saloon main building and gallows. Survivors at the main building generator or on gallows and knight/guard in the street.
