Quick correction to version 4.0! Looks like I should've spent a bit more time on 4.0 to make sure everything was okay :o
Seems a bug has slipped in the first operation: fixed here! There was an error in the Seraphim AI file which caused the function to mess up the game..
Also, Celene will now only build her T3 Artillery structures on easy difficulty. I originally forgot to add that difficulty restriction and added it like a minute before uploading, but it seems I didn't copy that to the .zip file before placing it here.. That should not have happened :(
Anyways, with this quick update, I hope you can all enjoy the first mission completely now!
