[Lose And Reset Of A Weapon In A Game]

Hi , today i've suffered 2 times of this bug :

For unknow reasons i've been disarmed (maybe an ennemy has this ability) but when i want to take my weapon on the floor the weapon stay on the floor and my char wear an invisible weapon (the same weapon ) but it level is 'unranked'. The weapon was 30 few minutes before. Fortunaly after the mission the weapon is at it normal level.

 

Thanks , Cya.
