If Anton is such a serious player, let him complete Xiedu. I haven't been able to do it yet, and I would be grateful to anyone who teaches this newbie, that is, me, how to complete it.

What's the problem? Create a thread on Heroes Portal for $300, for a couple of months. And you'll find masters who can help you complete it. No one will spend time just like that; I looked at the map, and it's more challenging than FB2.4 in terms of battles.

And regarding whether I will transfer $100, for me, it's not a question – my reputation is more important.

Wow, what a topic... on Heroes Portal, the discussion is calm and businesslike, but here it's just arguing.
And it turns out that the sponsor didn't give the money to the organizer before the tournament.
This has happened so many times in my memory when they announced a tournament with prize money, and after the tournament, the sponsors disappeared...
For the future, you need to receive the money before the tournament, give it to a trusted judge, and only then play.

As a sponsor, I gave my $ immediately to the organizer. medSTRAX promised an additional prize. He is not registered on Heroesportal. It turns out he was not even a sponsor, but just a person who wanted to give an additional prize to whoever fulfills his conditions. His conditions were fulfilled; perhaps he wants to check everything and sort it out. We are waiting for his questions about the game... But, of course, everything was just verbal, which is why there are disputes
