I don't know why GIB switched to the third best diamond at trick 2. Proper lead is 4th best.

Humans do it too

Of the 40 people on lead in West against 6♠, 6 failed to make a trick.
Plus 19 out of 64 in either East or West against 6NT.

In the example I gave, if you asked 100 novice bridge players, all 100 would cash the ace. 100 pros, too.

This had gotta be the same sort of bug that prevented cashing out on opening lead for -1 against slam in past versions of Gib.
BBO fixed it by put a statement they if such a situation occurs on opening lead cash out
but the underlying reason why cashing the setting trick is not consider the best option was never addressed.
This hand proves there is a bud in Gib's programing. Well beside the other bugs
