Wrong letter is green

I just came across a sentence where I started the word with the wrong letter, but because it was green I was misled:

The word is actually “riittää”:

As far as I can tell, “t” is the only letter other than “r” that turns green. And I never noticed this bug before with other sentences.

I just noticed why it behaved that way.

There was some text in the “Alternative answers” field: “That’s anough!” (including the spelling mistake, lol), and because that starts with a “t” it gets green color.

I don’t even know why it was there. If anything it belongs into the “Hint” field. Maybe it was me two years ago and I’ve already forgotten about it.

So, false alarm. Sorry.
