1st annual offline tournament "Best Of The Best"

Greetings to all tournament participants!
I started playing the map today, and a question immediately arose:
the rules state that you cannot use the Grail without open obelisks, but what should you do if the computer dug it up, and I took its Castle? At least that's what happened to me, and what should I do, replay the map? Because I won't be able to prove that it wasn't me who brought it.
P.S. By the way, the map is very interesting, but it's not very interesting to play it quickly, it's quite long, but I don't see any other option.

Happy first day of winter to everyone!
I hope it won't be long.
