Hey there,
I'm trying to open up my map with a short cinematic, kind-of like how StarCraft II single player handles their games. The title of the text crawl looks great, and the text gets typed in brilliantly (with sound and all). However, after about 50-60 characters when the text should drop to the next line, it just cuts off. You can hear the text still being typed, but the game does not display it. I've heard mention of using /n, which simulates the ENTER key being pressed. /n just seems to actually insert an "/n" into your in-game text. I can't see how I can get this to work - it almost seems broken, considering how non-intuitive it is.
Also, apparently there's an in-your-face, graphical three-second countdown timer as soon as the game initializes if you're using text crawl. I can't seem to make that go away. Any help is appreciated!!
None.
Contrast "/n" with "\n". You likely need the backslash "\" (Shift+\ is |, not ?), if that is the syntax SC2 uses.

I do stuff and thingies... Try widening and reducing the number of small nooks and crannies to correct the problem.
A linebreak in text is done via <n/>. Or you just hit enter in the text editing dialog.
The text crawl does not support more text than it can display, it seems. So, it can display approximately 59 characters.
So, you could either use multiple text crawls after another,
or you are using a dialog with a label with a text writeout duration. But a label won't be able to glow as nice as the text crawl.

Map -> Options -> is "Show game start countdown" checked? If yes, disable it.
