@^: I remember the discussion about character changes, but it didn't make it to the bug list since it's not a bug. I should have looked into it though.
I changed a few things that could affect test mode which I'll double check Your problem probably stems from the name change. Now that it's called
Knytt Stories Plus you need to change your Editor Settings.temp to reflect this. Even if you did, Windows may open the normal
Knytt Stories executable, which will give you this error if you have custom nature effects, The OCO's that don't require an image. I still haven't figured out why Windows will open the wrong program sometimes.
I'll add error checks for this scenario when I update the editor mod.
Edit: I found a bug while adding a fix for changing the character with shift-on-touch. If you stop moving at the moment it shifts to a different character, the movement sound will keep playing. Both of these things work well now. If you use a field of shift objects set to touch, then character changes and saves will only occur once while touching the field. I'd like to do this for any shift-on-touch actions, but then it wouldn't be backwards compatible.
I keep forgetting to mention this, I made the last Disk, object 11:11, a real object. It only appears in KS+ levels though.
