Insufficient Bid

Tony.

I’m not sure that I fully understand the new rules on insufficient bids. A recent example from our club: W-1NT; N-2♠; E-2. East hadn’t noticed the 2♠ bid and intended his bid as a transfer to hearts. In the event, East replaced his insufficent bid with a ‘pass’ and North played in 2♠. What are the correct options for E/W?
