Steps:
Create nether portal in overworld
Note the location of the nether side of portal
Reset chunk containing onverworld portal (not just reloading it, but completely resetting it to original state)
Make another portal in a different chunk, make sure it links up to the nether portal (If the new overworld portal creates a new nether portal, it will not work, you must make sure that the new overworld portal links up with the old nether portal.
Wait more than 60 seconds, or as long as you want.
Come back into overworld from portal in nether
You will come back in the spot where the first unloaded portal was.

I still cannot spot any bug - please read up on the mechanics here: Please also read the nether portal mechanics: https://minecraft.gamepedia.com/Nether_portal#Portal_linkage_between_Overworld_and_Nether
Please also try and optimise the world, and check if the error occurs after that.

Unable to reproduce, how far away are you building the other nether portal from the original one, does it take less than 60 seconds and what do you mean by point 4's "make sure they link"?
