I'm playing Beta 0.80.279796. I'm on windows 10, 16GB memory, Radeon Graphics RX570 8GB

Martin II is my 4th core world, I built a shipyard and then a colony ship. I decided to wait on launching the colony ship and when I got ready to do so I couldn't find my shipyard,

The next screen capture shows I did indeed have a shipyard.

I was able to get to the colony ship via the ship/fleet menu and send it on it's way. When i created another ship, I pops out shown below.

Upon selecting the sector to the left of the ship, I get confirmation the shipyard is there.

To the left of the shipyard identifier, there was a little pulsating object.  When I saved the game, exited, and then reloaded the saved game the next day, lo and behold the shipyard fully appears.  I guess the space engineers at Martin II finally finished their coffee break and finished the shipyard.
