Correct those are game bugs, after completing a level even without cheats it will not unlock the levels, also the achievements is broken sometimes it kicks back on and other times it stays off, that has to be fixed online and they are working on it.
I checked on the spore forums and several are saying after they do a fresh install and play the game normally wihtout cheating once, they unlock achievements.
But when they try to do a cheat, and than do something there close to get the achievement it doesnt unlock. But when they take the save, into install that a cheat hasnt been used in, the achievement is recieved.
I have the dame problem but I'm stuck on the Space stage where you have to start your own civ on other planets I have all the Badges and I have the Progress bar full but it won't let me finish the level.
theres nothing after space, and in order to finish i believe you have to like conquer the entire universe, and get to the core. not just get every badge, and get every promotion.
BTW my previous post there, correct... if you do cheat, at any stage of the game it completely locks the ability to gain achievements. other than the ones you would normally get like the play certain amount of hours 50+ or make certain amount of creatures or what not in the creator.
what do you mean by 'achievements'? I cheated in almost every stage (well not almost, I cheated in every fn stage!) and I also started using the trainer from the civ stage. I got badges, promotions, new equipment..well for me it seems I got everything you can get. Or am I missing something? I got some badges at the beginning for doing stuff and the rest I got by the badge cheat of the trainer. And by the time I started a new game (badge cheat is quite boring) and again I cheated in the previous phases und use trainers..and again I get badges, equipment..and so on.
