I don't think it was meant to run on the base facilities. I don't know why anyone would want to do that in the first place. You need to make a gameType, copy data > facilities.txt into your mod folder then run the editor on your gameType directory. Worked great for me.
Wow, great program. The Formula Wizard makes it stupidly easy to mod/create facilities now.
Only beef right now is a small one: the error message in the formula wizard, the bright colors are too much, and yellow on red is hard to see.
Really Dev, this is a great boon for the Se5 community. When this is finished hopefully the balance mod will get some competition

.
p.s. The Abilities section is just stupendous. Also, are you planning on going all the way with this, say, having a code editor for modding the ai_scripts as well? Or are you just doing the game contents? Either way it will be invaluable.
