Hi Kevin, I have the same issue (I recently moved from 1.15.2 to 1.16.1 and I deleted region files and chunk selectively to keep some chunks where huge projects are, and to reset the rest of the nether). I'm currently linking old overworld portals to new portals but I encounter the same issue: my overworld portal takes me to a place without creating portal on the nether side, and the location is the location of the old nether portal (which has been removed by deleting the chunks).

How did you manage to correct this ?
Thanks in advance
