OK, I've got my loadout sorted, and I've got all three passwords to the RAK. I'm ready to break the loop. After killing Harriet and sabotaging Frank's fireworks in Karl's Bay in the morning, I went to the Complex to sabotage Egor's thingy to get him to attend Aleksis' party at night. But I couldn't access Egor's control console, because I couldn't find any field nullifiers. Are they just not present at noon?

They are presents in the nearby building with the lasers raising an alarm.
