Hello Commander,
We know the change came only after the world was underway, however a solution to the disappearing bubbles required simply its time to develop.
If we did have a solution earlier, we would have deployed it much sooner.
We apologize for the confusion created on Firestorm 15, but we believe the change is benefitial and necessary.
We hope that players will come to realize this as well once they log back into the world and see that this is a less dramatic change that what it appears.
