I don't think this topic contains spoilers, nor do I anticipate the answer having spoilers. But I apologize beforehand if I'm wrong.

 

Here's my problem:

 

I'm at the Nar Shaddaa docks and I can't access either of the doors directely opposite pylons 2 and 3. Judging from the map, both doors lead to the same corridor. The doors light up green on my map, but when I go to the door no door-icon appears. It might as well be a blank unopenable door, if it weren't for the fact that they show as openable doors on the map.

 

So is my map wrong or is this a glitch?

Nope... that area is cut. There are some more areas in Nar Shadaa like that; but they are WAY better hidden than this one (and as bonus; do not appear on the map)

Thanks.

There are quite a few inacessible areas like ones you encountered in Nar Shaddaa that can also be found in Malachor's Trayus academy where doors are shown without being able to be opened and lead to almost no area beyond. Again, parts of levels in the game were cut in tems of content for TSL.
