I was playing Batcave Construct on an alt, was going for let the 3 Eradicators form during the Brainiac fight. The first one pop, would stun me but the little construct wouldn't come out, I kept getting stun but none came out. The second came out, I was being stunned by both, and on occasion would little eradicator would come. Eventually all three was up, I was being stunned, eventually, one form, then the second, I kept getting stunned, but the third one wasn't forming. I was soloing this since my cr was 200, going back for feats instead of purchasing with replays. I soloed this many times, never had an issue with Eradicators forming,
