I encountered a bug where when I take over Melee AI units (wether ingame via Zeus or via "Play as character" in the Editor) I can't use the melee weapon.
I press 2 to select it and it automatically holsters itself instantly.

PS: The Melee weapons work when I add them to my own Character via Zeus -> Arsenal.

But when I spawn an OPFOR Unit and give it a melee weapon and take over control, I hold the weapon in my hand but can't use it.
Tried different things like putting it into the inventory or on the ground and back into the weapon slot but still not working.

I'm not sure if this is a bug related to the OPFOR Side and it works perfectly fine for INDEPENDENT and BLUFOR or if it just works for Units set as "Playable" or "Player".

I tested it with a Civilian Unit and couldn't use any melee weapon while controlling them either.
