When I was super into Warframe, we had glitches all the time. A lot of bullshit disconnects, random "unable to connect" errors, but sometimes, they're just plain silly. There was one mission where my clan was doing a survival on some Corpus planet. We're running through this area, and one of my teammates comes around a corner and he's carrying his Archwing melee weapon in his right hand, as well as his primary weapon for his warframe! So there's this bright blue blade standing straight up, and his rifle sticking straight out. A few seconds later, he disappeared.

Then it happened to another clanmate! And then me! And then I disconnected from the session. We were all laughing about it, then we all restarted our clients and got back into the missions again.

All in all, lulz were had.
