We cut it close, and didn't leave ourselves enough time for simulations. But the Science Department pulled it off, as I knew they would.
The simple, inaccurate explanation of what we did is that we created a subspace 'firebreak' around the expanding bubble. Because the vacuum collapse was propagating faster than light, it necessarily was propagating via subspace; by destroying subspace ahead of the bubble, we blocked further expansion.
