@norcekri That would mean that either the SuperNova player hasn't successfully installed yet, or wasn't able to finish and take over playing .swf files. The browser should have an "applications" window somewhere that lists file types and what programs run them.
I don't see the "report missing achievement" link any more, but you can still report a missing achievement using the "contact us" link at the bottom of the page. They don't even require a screenshot for BOTD reports any more.
You might need to reload the game if your achievements aren't showing. The first time I loaded, it showed no achievements, even after playing a couple more rounds. When I went back, all of them appeared.
In the free play worlds, I'm often running into rebellious citizens who refuse to work, even when they're happy. It'll go days with every resource at "Your citizens produced 0 today and 0 yesterday", until the starving lot suddenly decides to work for a couple of days, restoring happiness, then stops, starves, and spends several days laying around starving again.
If your city is very big, it may be that citizens don't get paths fast enough from the pathfinding thread. In this case, you can maybe reduce this effect by going to the Game Menu > Advanced Settings > Increase the Pathfinding Thread Limit. Otherwise it's a bug (and I'd agree that it's not a great situation anyway, maybe I should just snail down the simulation if the pathfinding thread is too far behind)
