Rifle cleaning crash

[MudFlap33]

This happened a couple days ago and I forgot to report it at the time. I was cleaning a rifle, repeatedly. When I was about to bring it up to 96%, the cleaning just...wouldn't stop. I couldn't cancel it or quit the game normally. The cleaning continued for two game hours before I finally just force quit the game and reloaded. When I cleaned the rifle again, everything went fine, so at least it's not a repeating issue.
