No idea how it didn't bid anything here but it didn't.

You made a penalty double and partner honored that penalty double by leaving it in. Isn't that the way it's supposed to work?

I think OP means W should run somehow.

hmmm... that didn't occur to me... ick, either way!

sort of analgous to situation over jacoby transfers
does pass imply 2-3 diamonds, would redouble show 4 good diamonds?
at matchpoints could always be worth the risk to play 2♦xx for game bonus
2♦x a little less likely

GIB could always take the field play and just rebid 2NT just as if there had never been a double of 2♦,
which I would assume would normally be the consensus answer

Oh sorry I wasn't clear. I meant why didn't west bid something. If Stayman is allowed with 5 diamonds, 4 hearts, 4 spades, and 0 points with the plan to pass whatever response you get, then west needs to bid something here since east doesn't know if west has any points if west doesn't. I really thought west should have bid 2NT. Leaving it on a singleton opposite a 1NT opener pretty much assures that they're on a short suit, so 2NT would virtually always be easier than 2♦.

It's a bug because pass means 5+♦.

West has option between 2♠ and 2NT. Actually it finds them after simulation. Anyway even with no simulation it shouldn't consider passing with less then 4♦.

It will be investigated for fix.
