Forum:Unable to do missions

Okay, so I'm trying to get everything in the game and i'm close to doing it, too. however on space stage I need anly afew more bages but now i'm stuck. I can't do any more missions to get them. whenever i go to a planet and ask for a missions it says they have no more to be done. however i am able to do "change archtype" missions and the ones that come up suddenly like "your homeword is being attacked" but that's it! normal ones arn't working! does anyone know what to do?
