I need help alleviating a strange bug with Archimedes ships and Enhanced portals.

[DanielUSA]

My issue is:

 

I have an Archimedes ship that I wish to fly through an Enhanced Portal that takes me to the End.

 

The issue this causes:

 

When I fly the ship through the portal the ship teleports without me. When I go through, the ship is not there.

 

 

 

What I did to try and solve it:

 

I put poppit shelves in all the chunks the portals are in. Nothing.

 

I built 2 portals in the Overworld and flew through one and came out the other no problem. I tried vertical and horizontal variations of portals in the Overworld and had no issues.

 

 

I never found the ships. It is as if they warp to no mans land. If anyone knows anything please help. I spent over 3 hours building a helicopter to kill the Enderdragon. I wanted to video which showcased a few mods and use those mods against the Enderdragon.
