You can modify elin and aman chest also.. Honestly is pointless on elin but is fine for other class. I have created something for this is in testing but i wish submit it soon
Sorry guess I never replied, What I meant by that was using an address # finder and using the found number with a program and using that program to resize the chest. I don't know how to edit mesh and such so I couldn't do much more than rely on the program.
