Hello primius88.
First of all, thanks for your purchase!!

Ok. It´s a small bug easily removable:
Just change :
mText = dialog.font.WrapText(dialog.text, dialog.lineWidth /
dialog.cachedTransform.localScale.x, dialog.Multiline , false,
UIFont.SymbolStyle.None);
TO:
mText = dialog.font.WrapText(dialog.text, dialog.lineWidth /
dialog.cachedTransform.localScale.x, maxLines, true,
UIFont.SymbolStyle.None);
Let me know if works with this change.
Thanks!!
