Problem: If you accidentally delete screen message
files and attempt to re-import or re-capture screens to replace them,
references to the messages in those files may remain broken. This
is because for each screen message, a unique identifier is generated,
and this unique identifier is used to identify the screen messages
in other files.
Workaround: Back up your projects often. If you accidentally
delete screen message files and do not wish to re-model your flows,
bring screen messages back by importing the backed up versions of
the files rather than re-importing or re-capturing your screens.
