Been getting this error since one or more updates that Starcraft 2 has installed automatically when not specifically playing the game. Recently however I started playing it again with some friends and one of my maps was chosen for play, which was good but for a map problem that I’m unable to fix since one of the updates; as two of the files being requested are no longer on the system, although I have no idea why, as the map built a number of times on the same system last year. So I need help in figuring out what’s gone wrong and fixing the issue as when trying to resolve a map issue, the editor no longer builds and says that there are two missing files: TriggerLibs/MeleeHighAI.galaxy and TriggerLibs/MeleeAI.galaxy which some of the includes are for the AI scripting which no longer are present, though I don’t know why that has become the case.
