Condition A

1. Launch the "Spawn_with_launcher_and_laser_designator.VR" mission with the "play scenario in singleplayer option" in the Eden Editor.
2. Press the "switch gun / launcher" key and notice how launcher is switched to.
3. Press "switch gun / launcher" key and notice how it switches to laser designator.
4. Repeat step 3 and notice how primary weapon is never brought out.

Condition B

1. Launch the "Launcher_and_laser_designator_on_ground.VR" mission with the "play scenario in singleplayer option" in the Eden Editor.
2. Pick up the laser designator and then pick up the launcher OR run

player addWeapon "Laserdesignator_02_ghex_F";
player addWeapon "launch_RPG32_F";

in the debug console WITHOUT picking up anything off the ground.

3. The first press of "switch gun / launcher" will switch to the laser designator, the second will switch to the launcher, and the third will switch back to the primary weapon. This pattern repeats.

Condition C

1. Launch the "Launcher_and_laser_designator_on_ground.VR" mission with the "play scenario in singleplayer option" in the Eden Editor.
2. Pick up the launcher and then pick up the laser designator OR run

player addWeapon "launch_RPG32_F"; 
player addWeapon "Laserdesignator_02_ghex_F";

in the debug console WITHOUT picking up anything off the ground.

3. Notice how "switch gun / launcher" only swaps between the primary gun and the launcher, as it should work and how it works when spawning with those weapons in the virtual arsenal.

Note:

If condition A or B is happening dropping the laser designator and then picking it up will restore the intended behavior where keybind only switches between launcher and primary weapon.

I tested all 3 conditions on singleplayer, local host, and a dedicated server and the behavior was identical.

Bug may be related to or the same bug as this very old one that was reported.

Here are the very simple test missions:

I understand I can use the dedicated switch weapon keys that came with the new apex preset, however I use a Logitech G13 where the ability to switch between 3 weapons with 2 buttons ("switch gun / launcher" and "switch gun / handgun") instead of 3 is useful.
