When i die in the first mission with the SPR, the model of the weapon become invisible as soon as i relaunch or auto reload the mission.
So, i can't use the weapon at all for sniping because the cross don't appear in zoom mode.
And the problem remain "active" in other mission or campaign after that.
I can "solve" the problem by deleting the save game but it's not great...
