This is a new game started in Beta 6 Opt-in.  It still occurs in the latest version of the .exe (0.95.3.0).

While playing the game I got a notice of a ship battle that was immediately followed by a notice of a planet invasion before the ship battle appeared in the battle viewer.  The invasion played out and the game returned to the game screen.  I could not continue after that.

I had bought a ship in the shipyard associated with the planet that was invaded.  When the game screen returned, the turn button showed Orphan Shipyard and was grayed out.  The ship battle did not appear to have happened.  The shipyard was orphaned and the ship I bought was not completed.  I could do nothing with the fleet of ships that was supposed to be in the battle.

I could add sponsors to the orphaned shipyard, but they were not recognized.  The shipyard stayed orphaned.

When I decided to leave the game I found some choices grayed out.

I chose Exit, the game shut down, but the process was still running.  I had to end it in the processes tab.

Ticket #VXW-400-68009 submitted with all files and full details on how to reproduce the problem.

EDIT

I just tried it again.  This time I chose Quick Battle instead of Battle Viewer when the battle notification appeared.  Everything else continued as before except that the game was NOT frozen.  I could do everything normally and continue the game.

I'll let the Devs figure it out.
