Eh... easy... If you have Starforge you can save it as a... crap... I forgot which one you save it as... well the name anyway... If you use Starforge theyll be 3 choices. The first is like original or something and that doesn't protect it. The middle one protects it without damage to the map but the final release option? It protects it but pratically skews everything on your map including units and terran... Well thats what happened to me anyway. You could also use UBer@tIoN. Tip: If you protect your map and your not done... make another copy of it because not even you will be able to open it unless you're a hacker. Always keep a spare version that is unprotected to you can update it!
