OK, I tried your saves and it works fine on my end.
Now, I have another request. Could you launch your game, go to the faulty scene, then immediatly quit the game, go to your save folder, get the files named "Player.log" and "Player-prev.log" and send them to me?
I'll be honest with you, I have no idea why it wouldn't work on your end, but I hope these files may help me.
I also have a few questions:
What OS are you using and what version of the game (Win32, Win64 or Linux)?
If you're using one of the Windows versions, did you try the other one?
What kind of computer are you playing the game with hardware wise? Is it rather low-end or the opposite?
Also, does anyone get the same bug?
