Help: stop progression until all objects have been clicked on

I did almost the same as Carolyn and got it working too. Kept the layer same, but copied a new checkmark for it from another layer and then fixed the triggers.

These bugs are quite annoying as you can never be sure that if you have done a small mistake somewhere, or if everything is done right, but it is still not working. 

But I have seen this couple times when really there is nothing wrong states and triggers and so on, but the only way to fix it is to remove the buggy item and do it again. Previously it has been a trigger for me, so that deleting a trigger making it again exactly the same it was makes it work.

But this time it was not that, the puddle checkmark seemed to be the buggy item.
