After loading the old saves, have you been transported to the witch's hut?I updated to the new version today, and now when I go to fight, the game crashes. This is the error file I got when I tried to enter the catacombs:
Please try to send me your save files so I can see what is exactly the issue.
What you can try to do in the meantime is to rerun the old version, go back to the witchut save there and then export your save files to the new version.
Also what I have noticed in your sent error logs:
Windows-8-6.2.9200
Ren'Py 6.99.12.4.2187
Fall of Ashenburg 0.4
The game may haven't updated correctly to 0.5.
