Alphabetty Level 47 - bug?

Sara-2

In Level 47 I am suddenly not  allowed to create three letter words anymore. Or... Almost never and then suddenly one word works. The words I have tried are words that has worked in every other level. Only three letter words that work are the ones Alphabetty suggests when I pause top long.

I have the exact same issue that I am not allowed to create 3-letter words, only for me this appeared in level 58, about a week ago.

Only words suggested by the game are allowed, any other words are not, even the most common in my (Danish) language.

This is surely a bug that needs to be fixed by King.
