Hooray! I did it!
It seems something was broken...
I came to Keh again and this time he put the crystal into his device himself, I didn’t have to give it to him. A prompt sheet also appeared, like an ordinary buyer.
Then everything is simple, just follow the instructions on the stone.
Preparation will take 3 in-game days.
On the first day, you need to put half the sauce and half the cheese on the dough, then freeze it and immediately put it in a box.
On the second day, place the filling on the dough, freeze again and place in a box.
On the third day, freeze 3 times in a row and cut the pizza into 8 pieces. Congratulations, you've won!
