This is to report any issues with the experimental garden layout (saving copies of your garden layouts) feature.
This is still experimental, and I will not be able to restore anything due to data loss.
I can say, however, that this new feature is incapable of removing inventory. At worst, it may have issues with saving and loading where things are on the garden.
It's not exactly a bug, but it would be helpful to have an option to clear the garden of all items with a single button, now that we have layouts, or to be able to create blank layouts.
Once you buy the house, you need to go back to your my stuff panel (where it shows all the house selections), change it there, and make sure you save. If it still doesn't work after that, please let me know!
