I apologize if this is off-topic, but GMC has updated their combo:
https://www.gmc-logistics.co.uk/promods ... combo-1-53
With the following changes:
"Sinegor'e Map Add-on" has been removed (though you didn’t have it in your combo).
"Trans-Siberian Truckway" has been updated (possibly the reason for removing Sinegor'e).
"DE City Definition for Promods" has been added (apparently it no longer conflicts with the "Rhineland Map").
"Project Russia" has been removed (marked as "A lot of conflicts with a few maps").
"Road to Arkhangelsk" has been removed.
"M12_vostok" has been removed.
Oh, the endless puzzle of Russian maps...
