I've had a problem with this glitch for a very long time. It was frustrating because I'd spent an enjoyabl twenty hours or so with the game and then started running into the glitch in Omicron where you can't pass through a door as well as an invisible obstacle in the imfirmery room.

I looked around in the forums looking for help and tried some of the suggestions but nothing would fix it at least on my end. I haven't played the game in a year becuase of the all the frustration but when I loaded my game today I remembered what I had done. The last time I played I loaded an earlier game and approached Omicron from a different direction.

Originally and in a couple of retrys in an attempt to fix the glitch I would always enter Omicron from the front door. This time around I went in from the back. There's that bit of falling apart stairs and catwalk hanging over the abyss and once you carefully get down, there's a back door you can enter leading right into the dive room. When I picked the game back up today and started from this new position, all of those glitches were gone. Not only that but a few little elements including situational music showed up that I never saw or heard before so I think I'm in the clear now.

Maybe this will be of some help to others if they run into the same problems. I'm just glad to be unstuck now after so many head aches and being stuck a whole year on that spot.
