I had a normal portal system before, but today I decided to get ontop of the nether (the bedrock) and build a better\more organized portal system when I did it, I just moved the portals exactly on the top (I didn't change the X OR Z coordinators) just the Y.
So I got in the portal from the nether and it linked with the one at my base (home), that's great, but when I came back to the nether it didn't link with the one on top, it generated a new one, I broke the new one and tried again, and it's still not working.
Any ideas about how to figure it out? Besides than going back to the old system (not on top)
edit:it's not a duplicated question and that's why: I'm not in the ordinary nether I'm on top of the bedrock and i know that each nether block is 8 blocks in the over world and my portal is in the exact same location of the over world multiplied by 8 in the nether
