It happens consistently during chapter 1, after we enter the town for the 1st time, we enter the house where we have to press E to cross a little wooden beam and they both make comments about how high up they are. If the trainer is active, with or w/out any of the health, mana, ammo options on/off the game will crash. It also happened in 1.5 after opening one of the doorways by pressing E.
Where do i send the save game? I found a savedata file "Player.dfprofile". Is that the one you need?
