How do you build a...

[Dude]

cloaking facility?

Version 1.91 says in its history file,

4. Note - Spaceyards will not work on cloaked planets or ships.
5. Fixed - Cloaked planets were allowing you to add multiple spaceyards to them.
6. Fixed - A planet that was damaged and lost its cloaking facility would not decloak.
7. Fixed - A planet that scrapped its cloaking facility would not decloak.

And I'm like, "how do you build a cloaking facility on a planet?"

If anyone can help, it would be much apperciated.
