"But why TheGame?"
Because I still have to do Kerrigans Abilities.
All 21 of them.
And every time you select a Kerrigan ability in the editor, it freezes up for a minute because it has to load all of them, all the effects for all of them, all the actors and models (basically the visual effects), all the requirements...
Also don't worry about wraiths. The map was glitching up and in some cases, instead of making 2 of a unit (e.g. Marine) it would make 1 of them and 1 wraith. Hence the billions of wraiths that would never move out due to having no AI to them.
