I have several maps in the underground where spawners are almost next to each other when the 1.17 update comes what happens from my farms etc. Will they be deleted? There are myths that they will be removed?! What about my map where I built my base on a mine shaft.
Personally, I don't think they'll be deleted. In addition, the worlds that you have saved can also be played with 1.16, although 1.17 is already there, you can go to the 1.16 version to play in the worlds. I'm also not quite sure whether they will stay as they are in 1.17, but you can copy them so that you have 2. Then you can go into one with 1.17, and if everything is ok you can delete the copy.
