Edit : Thank's to BIS dev team to have fixed this bug with 1.2.x.y release ! 😉
Hello,
first sorry for my bad english.
There is a bug (at least with US faction but i suppose it's the same for RU) : when you load rocket launcher in a vehicle (car, truck), this vehicle becomes undrivable !!
Others players , do you have the same if you try, and if it is the case, thanks to BIS dev team to fix this frustating bug.
It seems the bug is this one (source : https://reforger.armaplatform.com/known-issues / General) :
RPG and LAW collider get stuck underneath the car after restreaming armed weapons inside of the inventory
To French language by google trad :
Le collisionneur RPG et LAW reste coincé sous la voiture après avoir redistribué des armes armées à l'intérieur de l'inventaire
Wish BIS team dev will fix it at soon as possible 😉
Because with US RPG there is only one rocket and no other way to bring more because of this bug.
Regards.
