In God of Monsters raid final boss(both Normal and Elite), the lightning chain mechanic can glitch in a way that makes it very hard, if not impossible, to complete. It seems that if someone walks behind Wonder Woman/Circe, the lightning chain will not connect properly, this is particularly frustrating in the Elite version since there's no time out that allows for a retry. Another visual bug can be seen below and this makes it hard to figure out the order, it occurs even when people were not messing the mechanic by moving around. The safest way to finish this is to stay in a line formation at all times, even when there is no call for such action yet. That's all the information I've got, feel free to add any other observations relating to this issue.
