The Forerunner sigils of the computer terminal in the Control Room (in both missions Assault on the Control Room & Two Betrayals) are glitched. Instead of symbols cleanly switching, they don’t transition to the next sigil properly and look rough as hell.

This bug is reminiscent to the numbers in the bridge in the level Pillar of Autumn that were broken by an update a while back and were later patched, yet this glitch seems to remain here.
