Crazyhouse castling bug

Are you sure the Rg1 is castled OR the King castled normally with Rh1 and then the Rg1 is pushed to h1?

The castling rule is that the King has to step two squares towards a rook. So with this in mind, the King cannot castle with the (dropped) Rg1.

But nevertheless it should be a bug, since castling is not allowed when a piece is in the way.

But I am not 100% sure about it in crazyhouse.
Pawn captured and dropped on the second rank do indeed have the same possibilities as the original piece. Hence likewise dropped rooks may castle just as the original rook could.

Dropped rooks on original square should alike pawn have same rights.
#5 - I tried, and he can't castle kingside in the given position. If you play a few moves further and develop your Q side pieces, castling there is possible. 5.0-0 is also possible, so the castling settings at the start of the game were ok.
