im getting the same problem with a villager who wandered into a portal. my version in 1.15.2, and i checked his dimension tags and it says overworld yet he is still in the nether :/ chunks are loaded on both sides, the overworld side being the spawn chunks. i have let him out of the portal for a few seconds, and held him in the portal, but nothing.
