I was exploring the Wasteland and I came across a metro entrance. I went inside, killed a few raiders, and went through a loading door that said it was to the "Jury St. Tunnels." There were a couple different doors that entered into different parts of the JST, and both ways eventually stopped me.

There was a message that popped up in the left hand corner saying something along the lines of "You should search the room before leaving..." I searched the rooms like a maniac, finding nothing of importance. When I left the room and went further into the tunnel, I ran into an invisible wall that stopped me from going any deeper. That happened in both locations, because there were two different doors leading to separate parts of the JST.

I assume it's a glitch because there were also a lot of flying dead body glitches; when they start shooting around the room and look like the ice cream man from the movie Legion. It happened to raiders and mole rats that were stuck in the ceiling. That place was really buggy.

I just wanted help. What am I doing wrong? How do I get passed the invisible walls without tcl?

Do you have Mods? I have only seen that "Search the Room" message once, and that was where the Mierluks are (Moira Quest). Maybe it pops up here too, but I don't remember it doing so. Anyway, in the Mierluk place, you have to look behind a refrigerator (activate it do so). You also only get the "Search the Room" message with a high perception skill
