I've just downloaded 3.7.4.
I have added the TypeWriterEffect to a label.
When I write the following code, for some reason if I have a . at the end of a sentence, it never gets shown..
_bottomDialogText.GetComponent<TypewriterEffect>().ResetToBeginning();
_bottomDialogText.text = "Whats up doc.";
Just shows
Whats up doc
EDIT : It seems to be other characters too, even a ! at the end of a sentence.
