Hello, there was an error in the guild archive. We were level 4, all perks were level one, then I set the tournament to two and the ancient wonders level was back to zero. This is definitely a mistake.

I've checked your game files, and you never activated Knowledge Sharing perk.

OK thanks for the answer. I was actually sure, too bad.
Best regards
