Tried using two instances of %i and had to add another “HiddenWord.Len()”.

else 
{
    PrintLine(FString::Printf(TEXT("The %i letter word has %i letters, dumbass!"), HiddenWord.Len(), HiddenWord.Len()));
}

I have a question: since this section is not done yet and will take some time until it is, should I move on to section 7: Building Escape or could this cause any issues for me (that I don’t understand parts of it for example)? Btw , love the course!

It’s a lot but seems simple enough.

I’m in this section, when compiling everything is great. When play the game I have a crash. It’s right after I added the %s with the *hiddenword to the fstring line in the beginplay function

Exactly like in the video says. Compiling is done and green… but when I press play crashes and the log is thisIMG_20190918_142020

Hope I can get help asap so I can follow the course.
