The save games works with Digital Deluxe edition and patch version 1.0.0.17
In the future, please provide some instructions on where your mines are, ideally a screenshot of the minimap with a red circle/arrow/dot indicating the places.
I indeed found that even though the mine was pillaged you were still getting the 8 aluminum from the 3rd newly conquered city. It wasn't until I moved a worker to the tile (2 turns later) that the amount was subtracted and the "pillaging" kicked in. This may be somewhat related to the bug where someone was given iron from conquering an enemy city with a mine prior to ironworking. It seems there's a bug in the way the game handles conquered resources.
