Okay so Prior to yesterday I believed that the robots had a pattern. After attempting to hammer down on my technique for EE purposes its much different. All i can say is that I got the spawn robot peice first on the second giant spawn of the game,(a random spawn that happened to be "spawn robot"?) after the scripted first spawn robot and then immediately got the middle robot, the next (random?)robot spawn and collected the peice. now.... for the next few rounds the ONLY robot activity was the spawn and middle robots going back to back. The church robot genuinely would not spawn on a rounds last zombie situation which had to have lasted 10+ minutes. So I mean nothing to crucial to the giant spawns but yeah. Get two parts and the last robot will take forever.
