The auction

3S x P 4H
P 4N P 5D
P 5S P 6H
p 6N P 7H
P 7N all pass

After the 4 H call, I wanted to ask about the queen of hearts and 5S was the Q ask. 6H denied the queen. 6NT set the final contract.
7H was impossible without the heart Queen. 7N to avoid going down 2 or 3.
No squeeze developed so 7N was down 1.

This is not the first time GIB reset the contract after Blackwood. It should not be that difficult to forbid GIB from doing this.

This is not likely a bug, because it's expected that after you've used RKCB over hearts that will be your future contract.

However, the next update will have opportunity human-player to override the 4NT designated suit and bid 6NT where GIB will be forced to pass as signoff.

It will allow to use 4NT as inquire over some suit, followed by queen of trumps and/or kings asking and then decide the contract where 6NT would be accepted as stop.

The steps would be optional as you can bid the 6NT directly after 4NT answer.
