After Zeratul Kills the overmind Kerrigan never gets out of the overlords to talk to him thus i can’t complete the quest. I killed the overmind with dark templar and cleared the map so not sure why it won’t proceed. Please help!
I figured it out, I had guardians in the way of kerrigan’s overlords flying in causing them to crash into each other and messing up the ending. Still Blizzard should fix this as it is a rare but real bug. Thanks!
. Nice discovery
