First off, I am aware of the issue with some sectors getting the homeworld icon when you have colonized planets there (and it has and continues to happen for me).

This one is a little different though.

Basically at some point over the last couple days my homeworld "lost" it's homeworld icon in the planets view, and a new planet was given the homeworld icon. This new planet I'm not even sure if I had a colony at previously, and if I did, it definitely did not have time to grow to the 400Mu mark as I have been monitoring other planets that I've colonized since the weekend change to growth rates.

All I remember is that yesterday/Sunday I saw this new planet with 400mu that I had never noticed before in my ownership, and now it has my homeworld icon instead of my real homeworld.

Should I be concerned that this is permanent or is this simply a display bug?
