At this point there is no real effect as you already lost a life. However, if you want to resolve this correctly you'll have to roll back to this Gobbo rolling a 2 and waiting for a response, with you still having 2 lives for this stage.
In this IBT, when you face Gobbo, you must use your risky attack -- in your case, that is the !magicblast command. Since you did all the post-Gobbo stuff in the correct order, if you properly beat this Gobbo, I'll allow the post-Gobbo actions to stand. (If this was a campaign like in IBT #3, then the post-Gobbo actions would also have to be voided and you'd have to redo that part too.)
Ohhh, I see. Thanks!
