I've encountered a bug, not sure if it's related to starting one route then going back to do the other.
I went to the TECH Shack, got the key, then backtracked and did the Power Plant route up to the jailbreak. The game then played both sets of dialogue (escape through maintenance tunnels and escape through warehouse), but when I went to exit it had both laser barriers up so I was stuck in the jail antechamber.
