Amnesia keeps crashing when I try to load my custom story

[Adrianis]

Can you list here the contents of your '...\custom_stories\' folder?
It's looking for the files in that folder, normally a custom story will have its own folder within custom_stories\ , and then the maps & scripts contained within a 'maps' folder, with a config file pointing to the starting map. I'm not certain how much of it is necessary (on my work comp atm so I can't test it) but it might be worth you replicating the structure & setup of a working CS to see if that might be the issue.
The errors are saying the map & scripts don't exist, so is it possible you've listed them incorrectly in the custom story settings config file?
