So I went into the nether for the first time through one of those already half built ones and spawned basically in a cave underneath lava. I said “oh great, it’s and spot”. As I exited the nether, it did not take me back to the one I went through but it put me someone in a ravine. So I made a new one near my base, ended up in the same location, exited, and now found myself somewhere in a ice biome! Please tell this is happening to others and no just my imagination.
