During the final battle after I have successfully set the dress on fire and the room goes dark I reloaded the game and it was impossible to set the dress on fire again. . You can see it in this video https://www.youtube.com/watch?v=a3JRxeBYPfU&t=4407s where the German guy has the same problem....

In the mine after Hansel loads a mine cart to jump over a gap he pulls a switch to open a gate. On going through the gate to the outside area of the mine if Hansel walks to the right a 'Fatal Error' popup message is displayed and the game crashes.. Have tried repeatedly with same issue every time. Is this a known error?...

Two things to consider: - more graphic options - less camera auto-changes, sometimes after camera change the child I'm steering is starting to run in complete different direction

As above

Thanks
