So ran EC story mode today. Took 5 attempts to down kephess due to additional bombers spawning during the third and final burn on the walker. Each time the additional bomber appeared it went right for the nearest healer and consequently wiped the raid.
I would like to know if anyone else has seen this happen, and what the cause of it might be? I did try more then one search on the subject and came up empty. thank you for your time.
Usually only get 2nd spawns if you fail to kill the 1st one in time. Sounds like a bug to me. Never seen it personally.
