My game stopped working after I found Triss in the Putrrid Grove. We left and went to Kluge's house . The problem occurs when Kluge tells us to leave via the trapdoor. Triss zones out and just stares as if she is in a trance. I climb down the ladder and after a while she attempts to climb down, but her body slides through the rungs and she goes into her trance stare again. I went to the canal and walked down and when I get there under the bridge she shows up. She screws up again climbing the ladder from the canal to the street. Again I left her after she became trapped between the rungs again.
I walked alone to the fat flour merchant and she appears again, but a second later the game bombs. I cancelled the game and deleted the games file and restarted the game and again after three days at the same point it does the same thing.

Another bit of weirdness. I have two Redainian halbediers and normally they are red. Both of mine are light gray. Something is wierd in GoGland. I also verified the game files three times and each time it says the files are good. I also ran a new chkdsk to check for drive errors on my harddrive and two different programs told me that there are no errors on my drive. I am at a loss as to what is going on. I have played Witcher 3 four times on Steam all the way to the end with nothing like this happening on this same computer. Steam sucks with no way to contact them about problems so I left them. Does anyone else have a problem at this point?

That's definitely a corrupt installation and/or save file.

1. Do you keep discreet save files as opposed to quick saving all the time?
2. Do you have any mods installed... ANY?
3. Do you use, or have you ever used, the console (commands) during this/these saved games?
4. After verifying game files are you loading old, previous save games?

1, 2 & 3 Yes

4. No. I completely deleted all of my old games before I began this game. I will check my mods and see if any of the new ones are the culprit.
