Hey everyone, after updating to the latest Unity patch 2017.2.0p2, I sometimes encounter the following assertion errors after closing an editor game session in play mode: Assertion failed: Transform has SetIsDispatchInterested present when destroying the hierarchy. Systems must deregister themselves in Deactivate.

I've never seen this before the latest patch. Any help is much appreciated. Thanks.
