I am hoping they clarify if this was a bug in the game that will be fixed, or if Peter was incorrect and it doesn't freeze adjacent. Really seems like it should be the former based on all the other interactions, but would be nice to have official confirmation.
It was a bug - will be fixed before the expansion launches. Sorry about that!

It was a bug. It should be freezing the adjacent minions as well. We're fixing it now! :D
