Invisible Guns

[PoosKi]

Hi, 
Recently a lot of players have complained about their guns disappearing in JB.
This just happened to me today and I did a knife fight with a friend in HG, but ended up killing him with my gun because I didnt know what weapon I had.
Please fix this, extremely annoying, and inconvenient.
Thanks

This isn't only JB I think, I have recently experienced this on competitive as well.
