It's a save file judging by the filename. Awakening is the very first level of the main campaign.

It's useless without the associated .META file though.

Imps have a problem seeing jobs beyond a certain distance. If you were to pick the idle imps up and drop them in the tavern, they'd start collecting the gold.

The tooltip specifies that it is only disabled in Heart of Gold.

"Channels your essence to complete all constructs across the entire map. If a construct in damaged during the process, it will not be built. In the Heart of Gold campaign Construction cannot be used to summon Outposts."

The combo works in Skirmish mode and is nigh useless in the main campaign anyway, and definitely does not break either of the two levels it's possible on (Last and second-last). I am 100% certain it is only supposed to be disabled in Heart of Gold, as almost all of those levels can be broken using it.

It's your call though.

Had this issue during a HOG level after loading a save.

Tagging and then untagging reverted the colour to normal.
