I cannot complete the game if it's not going to let me move the Marker. I restarted the entire game and same glitch. I can pull it *backwards* easily enough, but not forwards into the room. Today, no matter where I kinesis it from, it will not budge. I also recently read the plot of Dead Space: Martyr (a prequel novel) on the wiki, and it points out that someone elses hallucination was saying to destroy the Marker on Earth. I had no problem pulling it across yesterday. In DS1, the marker hallucination (Nicole) kept giving us instructions on what to do with the Marker, which turned out to be the way to contain the Hive Mind.

Or I tried to, because it froze on the tracks. So I dragged it past the damned bridges again into the L-shaped room.

Today I open the game and the Marker is back where it was BEFORE I'd dragged it past the two bridges. I saved after finally getting the Marker past, then quit after I'd dragged the Marker past the next L-shaped room, into the open area, and quit after I realized I was too tired for another tentacle fight. I had a hell of a lot of trouble with these two in particular not freezing, getting stuck halfway open with no way to bring them back down except restarting.

In the last room I was in, there was the big round entrance to the giant fan, and two bridges I had to lift, freeze, and push the Marker past.
