Needed chip to progress doesn't appear

[Romulator]

The fact that that one turning chip shelf is missing makes me believe that's where it was supposed to be, then something stupid happened.

Verify the integrity of the game's cache (See Problem I) in case you're missing the entity, then choose Load Game from the Main Menu and choose a slightly earlier save from Site Theta. It should reload the level and hopefully fix your issue.

If not, I'll see if I can provide a save for you!
