AI would get stuck on "get in vehicle" animation on cDLC and modded vehicle, and swapping seat also have issues.

[JXKun980]

Describe the bug:
When using the menu to order troops to get in a vehicle, sometimes one unit would get stuck in an infinite loop of "getting in" animation. Ordering troop to move would unstuck them and allow them to move to the waypoint but they would go back to the vehicle and start the animation loop again afterwards.

This is only evident using the command menu from this mod, using vanilla command menu do not have this issue.

Initially evident using CUP mod vehicles, but later found to be evident in the cDLC Global Mobilization vehicle as well. Haven't tested on vanilla vehicles, not sure if it's just the modded vehicles that have this issue.

Aother issue is that when ordering the troop to swap seats within a vehicle (e.g. gunner), they would pop into a bugged place with wrong animation.

Update: Confirmed that vanilla vehicle do not have this issue

Steps to reproduce:
The following steps are tested on cDLC Global Mobilization.

For the animation loop bug:
Spawn a group of units
Spawn an empty APC
Order a few troops to get in by selecting troops using F2, F3, F4, then press "4" to bring up the menu, selecting "tracked vehicles", selecting the APC, then "anywhere".
Some troop would get stuck in the animation.

For the swap seat bug:
Select the troop already in a vehicle
Press "4" to bring up the vehicle menu
Select the current vehicle at the bottom of the list
Select "Gunner"
Unit would pop his head out of the APC but at the wrong place
