The files are fully compatible since 0.x. If you can send me a link to your warehouse.json file somewhere I will have a look.
As this is an elementary fail, every single player would have complained so I am curious why it happens only in your case. Maybe an edge case worth exploring.
Delay that action;)
Just to make sure:
You are aware that you cannot go back to a 1.4 save without running 1.4.If you try to open 1.4 save in 2.0 it crashes. Actually it should never have loaded the save game in the first place and informed you.
Yeah, I'm aware of that - I have both versions of the game downloaded and just ran 1.4 to try to move my items from 1.4. I just sent you a message with a google drive link to my warehouse.json file!
Edit: nvm, can't message you. I'll just post the link here: https://drive.google.com/file/d/1hwER4HlP41vLp1pDVOop209ONK9h-9Hb/view?usp=drive...
