Crowns disappearing

This happened 3 times since I started playing on the en72 server. I am losing crowns without actually spending them on anything. I contacted support and I've been told I am spending them on "commerce, buying wood clay or iron". I assume that means I am using instant trades but that mod doesn't actually know how the game works. I am pretty sure it's instant trades because I have been losing them in chunks of 50. Any more experienced mod can check I have all my instant trades items in my inventory so I can't even use crowns on instant trading.

I lost 200 crowns so far I really hope I'll get a refund soon.

Thanks. :)
