So the issue I have is that when I enter the nether it takes me to the portal there where I've explored and built. however when I go back to the overworked it randomly spawns me somewhere with no portal back.

i don't know if the version is correct for the platform I'm on but I'm on Playstation 4 and just got the caves and cliffs update which did not fix the issue. like I said in the summary, the ner portal works going into the nether but when I leave it sends me somewhere random with no exit portal. it sent me to these coordinates once which were absolutely ridiculous: 6564, 68, 16442. at least I write down all my important coordinates.
