I'm just trying to load a save file every save file keeps giving me an error even when try to use a fresh save
odd, what version of the game are you using? I vaguely remember encountering the same problem. I'm pretty sure you need to first port your save over to the latest version (CoC_Xianxia_0.8s5.172) which is only available on their bugs channel.
there's also a few gimmicks you need to keep in mind of when using the save editor
First of all, for some inexplicable reason, whenever you would change anything in the save editor, it would revert your backpack size to default (perks not counted). Simply empty your inventory before using it, uncheck "Backpack" in Key Items (Save Editor) and once you're finished with your edits, repurchase the backpack from Benoit.
Secondly, you cannot directly add items into your inventory. When you need to add things, use the "Storage" section of the save editor instead. I haven't checked what you can and cannot put in specific containers, but I found that the "Warehouse" works for anything.
