So I'm having this issue with Nether Portals linking. Put simply, the first time I go through the portal every time I log in (whether it's from the Nether side or Overworld side), it always creates a new one quite a ways away from the one I made. Every subsequent portalling after that always go to the correct Portals. So just the first use per session.

Details that may help:

• Overworld Portal (225, 61, 400)ish
• Nether Portal (23, 75, 51)

So by my knowledge, that is darn close enough for the game to find it everytime. Yet it has taken me to these locations..

• Nether -> Overworld (21, 64, 58)
• Nether -> Overworld (31, 78, 41)
• Overworld -> Nether (220, 64, 408)

As you can see, these are way off. How a Portal in Overworld at 221, 61, 400 ends up in the Nether at 220, 64, 408?

I've tried breaking and rebuilding, to no avail. Only thing I can think of is either this is a bug in current version, or bedrock isn't kind with custom Portals? My Overworld Portal is about 15-20 blocks tall, and 3 wide.

Images provided:

1. Overworld Portal (Lower portion of Portal, Portal 20 blocks tall)
2. Nether Portal
3. Random Nether spawn after going through Overworld Portal
4. Random Overworld spawn after going though Nether Portal
5. Same as 4.
6. An image of the upper half of Overworld Portal, for reference, in case a custom Portal is the issue.

Edit - My apologies, it seems the pictures were posted out of order. However I believe they can be made sense of regardless!
