HD mod, question about save files.

1. Please excuse me for the vague title of the topic. 2. I have attached the map 3. The point is that the map is XL size, with a dungeon and a lot of strong monsters and quests related to them. We are playing with a friend in an alliance against the computer, so we can forget about cheating. I removed this level restriction in the map itself, but I don't really want to replay it from the beginning. I thought that maybe someone knows a "simple" solution to this problem, so that we don't have to launch ArtMoney every time.
