This morning's update fixes a bug that caused the old and new versions of the sandwich maker puzzle to overwrite each other's save files. If you intend to continue playing both versions of the puzzle, you should make sure that your existing solutions for V1 of the puzzle start with "personal-sandwich-assembler" and your existing solutions for V2 of the puzzle start with "personal-sandwich-maker". New solutions will be named appropriately and will not experience this issue.
