The Meaning of Life, the Universe, and Everything.
Ok so first, keep in mind that bastions only spawn in the Nether Wastes, Soul Sand Valley, Warped Forest, and Crimson Forest biomes. If you can't find it immediately, keep exploring in those biomes until you find it. Just keep in mind that some bastion spawns are different from other seeds. The same applies to nether fortresses. Sometimes you build a nether portal that spawns you right in the middle of one. Other times, you end up searching for an hour for it. Hope this helps!
