It's not there anyway; it can only be obtained in the right castle.

I know that's why I asked: REMOVE the restriction on the appearance of the guild acceleration. Although, if that was your original idea, then it's your right – after all, you're the author.

It's interesting to know if anyone figured out the main feature of my map on their own (only a limited number of people know it).

How can you tell if it's the main feature or not? After all, there are many features on this map, and it's unclear whether it's the main one or not? ;) At least give a hint. Otherwise, I might be playing in a tournament on this map soon, and I'd like to know about your "main feature" before then.
