Have you been to Hex F1 first? You need to get the tip that Q lives in F2 before having a chance of finding the bunker.i've tried both of those and still get stuck with that glitch. i just want to unlock the hatch to move on...
If you did, then this should unlock it (if you have at least 3 sierra club points and you search the fields), open console and type:
foundbunker = True
