So if you create a nether portal, it creates one linked in the nether, if you create another portal within 128 256 128, the nether portal will take you to the first and closest portal, which is going to be the first one. If i understood the forums correctly this process of un-linking portals is broken in some way. I created two portals in the over world both are within the 128 256 128 range, when i destroy the first portal created, the nether portal does not instead link to the second one, it creates a new portal within the area of the first portal. In the picture provided it may help clarify what i'm describing. In the overworld there are 2 portals within 128 256 128 and they are both linked to one in the nether, if you break one of the portals in the overworld, the nether portal does not link to the second portal created (The closest one), it instead generates a new portal within the first nether portals area and this allows for infinite obsidian generation as well as much annoyance.

The nether portal isnt taking me to the closest one WITHIN the radius. It is instead creating a new one in the exact spot that it was broken in. This is an issue
If this issue is proved false then the wiki needs to be corrected. Please fix which one it is because this is a bug.
As far as I can understand (from that video), the behaviour is working as expected. Just to be clear, are you talking about linking to an un-activated portal?
So i have 2 portals in the over world. They are about 100 blocks away from each other, both are linked to one in the nether. When i break one of the portals in the overworld it doesn't make the nether portal in the nether default to the one that i didn't break that's within range. It instead creates a new portal where i broke the other one. - It may help to know that this is on a lan server, so someone else created the one portal im trying to break
Yes that can happen. When you created the first portal, as there was none in the nether, it created one in the nether within a 128 horizontal radius. When you enter this portal in the nether, it then searches the overworld for a portal within 128 blocks. What happens is, because of the 1/8 scale between both dimensions, the distance calculation isn't scaled, so while it finds the portal going into the nether, going out it doesn't see it.
Nether portals do not 'link and unlink' themselves. When travelling through one, it connects to the closest one in the Nether or overworld, to a 1/8 scale. See the Minecraft Wiki article on this for a good explanation of the process.
