I noticed that after the recent Destiny 2 update, when in the crucible if I swap guns, all my guns become invisible with no scope/reticle to aim with. I also notice enemy guardians becoming invisible, see the link. I thought it was my video card, so I rollback the drivers to 3 months ago. I also thought maybe my hard drive was dying so I installed Destiny 2 on a different hard drive and I am still having the issue of invisible guradians.
