Story of how it all happened :
I joined a party at depth 13 of the Diamond Pawn gate. There was a Mega Magnus recipe Basil was selling, but i could not buy it because i had just joined. So i gave player Wundt 10,000 crowns and asked her to buy it for me. She bought it, and then traded it to me. I then went down to depth 14, and everyone else went up. I kept playing until i got to the end of T2 at depth 17. There was an alchemy machine there, so i thought i would make my Mega Magnus. But when i looked in my inventory, my recipe wasn't there. I even looked at all my learned recipes, it was not there. I do not know if player Wundt still has the Mega Magnus recipe, if she does i would like for you to take it from her inventory and place it in mine, and if she doesn't i would like for you to send me a Mega Magnus recipe.
Sorry if i did not need to go that in-depth, i want to try and make everything as clear as possible.
Thanks.
Player Wundt has replied to the mail i sent her asking if she still had the Mega Magnus recipe. She still had it and has given it to me, though you might want to still look into this, i don't know.
