It would have been REALLY NICE to know that was the Canadian OOB you were looking at and It would have been REALLY NICE to know the LBM numbers but I "figured it out"......eventually
Troopie ( and me and everyone else..... ) did not see the "red" dots because they cannot be seen in desktop mode. They have to be enlarged 500% to be seen OR you run the Windows Magnifier
They are the result of a change made to the palette not recently but
YEARS ago that replaced a little used dark purple with a more useful rust brown (Game palette index #201)
.......and the reason they are still there is they are invisible to (apparently) 99.9% of the players
EDIT
Just for the record, there were changes made to the game palette during early DOS development mainly for the main greens and the colour of water then another for the windows versions in 2005 and then another in 2016 and finally again in 2021.
The one that changed Game palette index #201 from a deep purple to a Dark Rust Brown was made in
2005 ( 17 years ago........) so that's how long some of the PIC's have been like that
