[bug] Can't finish the game, Railcar murder bug

[GrungePunkNick]

I "finished" the game, but was missing 2 "missions".
I'm playing the redux version

Railcar murder and the House of Mirrors(Fake Interiors)
Went back, finished the Fake Interiors or House of the Mirror mission, got the achievement.
Went back and also finished the Railcar murder, everything happened... I saw the flashback and the messages and even got the achievement. Got back in the portal.

But it still says that it is missing the Railcar Murder solved.
I went back, watched the flashback again... nothing happened. Moved the railcar and tried again... nothing. I beat this mission but it won't say that I've done it.

What to do?
I'm in the Vandergriff House where there is the map with the missions but I can't go on :(

This. There a column with lights in the forest ahead of the location of the last scene, before the train station. You have to find that to finish this part.
