More details in this [Link Removed]
I’ve uploaded a test project on 5.7-release. When several Geometry Collections are connected by assigning the same Cluster Group Index, Chaos break event fires on the first frame regardless, even though nothing has actually broken yet.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-367481 in the post.
