Just a small glitch that I thought I would warn others about.

May contain slight spoilers for those who have't been to Blackreach yet.

If you are exploring Blackreach and get to the Raldbthar Deep Market entrance, there will be a Falmer tent to the right with a couple enemies, do not try to enter the tent! If you somehow managed to slip in without problem like I did, you will find yourself stuck inside. I had to reload to a previous save from like 15 min earlier :/, and when I reached it again I noticed that there seems to be an invisible wall blocking the entrance of the tent, idk how my character made it past it the first time.

So, if you find this tent, just kill the enemies and don't try to enter it. Here is a screenshot of the tent I'm talking about, even though it blends in with the rest of Blackreach lol. http://img832.imageshack.us/img832/871/screenshot71z.png
