Allright - i might be missing something very obvious or i havnt fully understood yet how portals work - so i thought i better ask in here:I wanted to setup a portal outside of the frontier east protected area to shorten the way to my frontier area via a path in the nether. I end up at a hub obviously created by the people living in cliffside etc - will say to the north of that spawn - i intend to go south from there. I am greeted with signs 'dont remove anything else...' - but the entire place is sealed without a single door to get out of the box. I tried to setup the portal a bit further away but still end up at the same hub every single time. What am i doing wrong here?Edit: I was of the understanding that i would create a new portal as long as i am more than 128 blocks away from any existing one - and i am pretty sure i moved at least 200 blocks away from the protected spawn area.
