failure to display error or recognise correct solution?

Re: Oryza sativa 4 - difficulty level 0

shows no changes in structure while switching from the frozen to natural view and back again (see the composite image or the side-by-side view) but it is shown as not meeting the completion criteria (although manually counting it contains more than 10 GU [red-blue] pairs).

Is it not a solution but the game is unable to display why or is it a solution but not recognised as such by the game?

Looks like you haven’t satisfied the GU (red/blue) requirement. Mouse over the red box with the GU pair in it to see.

Hmm… Maybe there could be a user interface element that emphasizes the GU pair requirement when all other requirements are satisfied?
