Great question, Ryan.
Yes, a gap is formed. There is a Card Abilities reference card included in the game, and this situation is handled on the card.
If the Rift is split into two or more groups, the largest group remains, while the rest are removed. If one or more groups of tiles are tied for number of elements, the player who caused the split choses which group to keep in the Rift, and removes the rest.
Thanks for your question, Ryan!
Is this also another update to the rule?
The rule states:
In the event that two or more groups of tiles are no longer connected, the player who caused the split chooses one of those groups, and removes the remaining tiles from the Rift.
It does not require that the large group remains.
