If you rotate a Cloud Chest or a Static Cloud Chest with a balloon attached to it, the block will rotate and a new balloon will appear. This does not occur with Balloon Stands.

Happens in both a multiplayer modpack and isolated, fresh instance with only Cloud Storage and Immersive Engineering. Tested using IE's Engineer's Hammer.
