Halo 4 Galileo Glitch

I was play Spartan Ops EP:3, CH:2, Galileo, and everything was going normal until the last objective of the level. I died from a headshot and when I respawned, all the enemies were seemingly invisible, or they had fallen through the map. All you could see were their guns, which were just above ground level. Plus they were moving around as erratically as possible. The only way to kill them was seemingly with grenades.

This wasn’t the case, however. I eventually saw one up close when it stopped moving long enough to get a good look. They were still there, only impossibly small: about as small as the game could render them. They were basically the size of the bullets I was shooting at them. It was fucked up to say the least, like some alternative Big-Head mode. I tried to record it in my file share, but it only save Wargames matches.
