The Nintendo Switch just got a new update that adds Virtual Game Cards as a way to share digital games with other people. But the update also closes a loophole that would let you play shared games online at the same time as somebody you were sharing the game with, as reported by Eurogamer.

Here’s the full list of changes in Switch firmware version 20.0.0 which went live on April 29. In addition to adding virtual game cards, GameShare for Switch 2, and Switch 2 system transfers, the update also allows for save data from multiple games to be transferred simultaneously.
