Stuck in Bree! Glitch?

[Wandalf the Gizzard]

I was exploring the Middle-Earth open world (Bree location). Having found all Mithril Bricks in the area, I attempted to leave and head for Weathertop. Well, the only way out was through the small door facing back to the Shire! (there is a wall around Bree preventing you from going around it, otherwise that's what I would've done). Usually there are two large open gate on the North and East sides of Bree, but they were both closed for some reason this time! The only way I could get anywhere other than Bree or back to the Shire in that particular session was through using the Map Stones.

Is this a glitch? Is there a way to open the gates that I'm missing? It's not too big of a deal, since I can always use the map-stones.

I think there is an open hole in one of the walls that lead to weathertop but Im not sure.
But changing time from night/day should fix the problem...
