All quest-glitch shall be reported in the quest problems topic, not in the game's quest-discussion topic.

Anyway: the "Nothing to do" quest becomes active AFTER you have 100% everything AND start a new game (after you finish the campaign it has two button: "not do anything" and "new game". Push "new game".
Also, any quest only becomes accepted after you finish the level, not for example at the moment you summon Kruggy.
I did twilight2. Several times, several months. No reaction.
Also I have reached 100% in one playthrough. Started a new game => No "Nothing to do". I played this new game to 100%, started a new game (again) => No "Nothing to do". I played this game multiple times with all hints in this forum => No "Nothing to do". Tell me step by step what I should do and I'll try it.
So I finally achieved the "Nothing to do quest" !!!
First of all I have to say that I tried this quest x times in Chrome but it didn´t work so I decided to play a NEW GAME in Firefox and Local save !
So if you have saved position then start over to have zero IN-GAME achievement !
How I achieved it: 1. Completely destroy every town(skull icon) (in Santa´s island too) except one (I chose Vancouver because of fast money) and then ignore "new game+" option and click continue, 2. From the last standing town (Vancouver) collect money for all upgrades (you don´t have to upgrade all the zombies to the max!), 3. Now you should have all in-game achievements except "Infectonator!", "Behold the Lord" and "You have nothing", 4. If you are fully upgraded and there are only 3 achievement left mentioned above then completely destroy the last town, 5. Ending scene comes and then click the "new game+" option, 6. Now the quest "Nothing to do" should pop up!
If there are any questions just ask but this is the exactly the way I have obtained mentioned quest.
All hail to Thomcore. I finally was able to achieve the Nothing to do quest! I did exactly what he said above and it popped up! Don't know if you found a workaround or they eventually reacted to my "lease fix it" spams...
@SonicTheHedgeHocBam lake a look at the laboratory, top right you have 3 options "support" "zombies" "upgrades", selsct zombies, buy/unlock some, then you cna use them at the maps.
i have beat the game 3 times (yellow skulls, destroyed symbol) and you unlock a new zombie everytime you destroy the world and restart, first its bomber, then brain jar, then the pucker. i don't know whats next. I've also gotten all quests. The game is hard, but it also takes time. GREAT GAME
You fulfill all it's side missions, like killing X people with Trap Y.
Collect X gold or Summon Zombie Z.
Now just like everyone else I had to play the game twice because of the Middle-East quest. Pretty annoying that one achievements in-game doesn't unlock. And that leads to the last last quest not be awarded, the one about all achievements.
I've playing this games for 5 times consecutively today and I still can't get that ANNOYING "nothing to do" quest because the Infectonator! (ingame achievement) shows up as 100% not completed EVERY TIME I destroy all towns and the game ends. WHAT DO I NEED TO DO TO GET IT?
