I do not know how actively GOG's staff browses the game forums, but I would like to ask the team to update the build of Total Annihilation and add the missing 6 units that were released by Cavedog after final path3.1.
List of units:

I would be great if GOG version would be the complete and did not require downloads form third party websites.
