When setting up a new world, I definitely chose to create a bonus box, but it is not created. So I thought it wasn't created because of the mode crash, so I took out the mode and tried to create it, but it wasn't created again, and I thought it was because I didn't find it created between trees, so I tried it on the plain, but it wasn't created the same way. After 1.17 was updated, there was no bonus box and I hope to fixed it.
