Castling Bug - Not really

This is for a note in Chess.com Beta by @Reyc14 claiming there is a bug when playing against Computer3-HARD.

The claim was that while attacking b1, the computer still castled long, even though he attacked a square between the rook and king.

Misconceptions of castling rules:

It is a common misperception that the requirements for castling are even more stringent than the above.To clarify:

• The chosen rook may be under attack.
• The rook may move through an attacked square, provided the king does not. The only such square is the one adjacent to the rook, when castling queenside.
• The king may have been in check earlier in the game (provided the king did not move when resolving the check).
