I am sorry if I get this wrong....but you can place multiple things to come out of 'named location'. Like one minute you could have zerglings coming out of 'location 5' and then 2 minutes later have hydras come out of 'location 5'. Its in the matter of triggers for that one. I have messed around with quite a few games and found out interesting things. You should also be able to do this with the default editor. I have done it myself for a Blue Gender Defence/Attack I made some time ago. No one ever plays it so I deleted it.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
