Thanks for pointing this out and giving a detailed description. I've made a note of changing the save location.
I don't keep my eye on the linux version, so is this something that is reasonable for all modern distributions?
Yes, the XDG standards apply to all distributions. This would not negatively impact anyone. The only question is whether you implement it so that it copies from the old location if there is no save in the new location. Personally I don't mind.
