I have never seen anything of this

Really weird!
Do you receive new elements on an understrength unit or new units on a stack??
For attaching files here, go to
C:\Program files\Wars in America\WIA\Saves
Open the apropiate folder there (in this case it would be called something like 1756 campaign)
If you have started several 1756 campaigns check the folder time stamp.
Inside you will see 4 or 5 files (the current turn you are playing) and up to 24 sub folders with names Backup1, 2, 3... (it depend how much turns into teh campaign you are)
If some of this strange thing you explain happened on the last turn Lodi will need all the current turn files, plus 1 or 2 backup folders.
The ones called backup1, and backup2 are the two most recent turns after the current.
If this happened some turns before you will need to attach older backup turns.
Select the backup folders you see fit and the current turns files and compress them with your favorite compression program (winrar, winzip...)
Attach that compressed file on a post of this thread using the "paper clip" icon button you have over the reply box and the upload file menu you will get.
Hope it helps!
