Hello, I have a minor problem. When you locate when Triss teleports you to the Salamandra crap there is a fight where there are people as they teleport and come out of the tama reinforcements and I have a problem when I start fighting so the game will fall and I have already happened several times I have already checked files, I thought I'd uninstall the game, but I'm afraid I'm going to clear all of my saved positions. So please advise on how to fix it. Thank you in advance for your reply.

I'm not sure about your specific crash problem, but savefiles should be stored in a folder in My Documents. You can back them up in case they are deleted during reinstallation.

Incidentally, deleting old files usually helps to prevent crashes in late game, but if the game is crashing every time at the same point your problem probably lies elsewhere.
