Well, the subject pretty much describes the problem. The signs outside the portcullis indicate that it is supposed to be open from 8 AM to 8 PM, but that never happens. I have had my character stand there for all 12 hours and nothing. The NPCs try to walk through it, but they just get stopped by it. I'm able to get past it with the console cheat 'tlc,' but I figured this should probably be addressed.
