Hi,

save-place-mode cannot restore last saved position when
`save-place-abbreviate-file-names' is non-nil:

- emacs -Q
- M-x save-place-mode, and set save-place-abbreviate-file-names to t
- open a file, scroll to some position, and kill buffer
- reopen the file, the position is not restored

The reason is it uses abbreviated file names when saving positions to
`save-place-alist', but uses full file names to find position in
`save-place-alist'.


Best,
Liu Hui
