BB5 Question on Haven Attack

New to Phoenix Point, haven’t played earlier Builds. Question – just saved a Haven from attack. As I was leaving to go elsewhere, the Haven was immediately attacked again! Is this a bug, or is this designed to happen on occasion? Thanks!

Never happened to me.

I have had a haven be attacked while my soldiers were still recovering from the last attack. But not as I left.

There’s a thread in feedback talking about this.
