It should be fixed now on v0.2.2. However, I face a problem, it is a limit on how many characters (points in this case I guess) can be rendered at once onto game textfield. Technically is 65KB, that's what I read on unity forums at least. But on my tests I can't move above ~16KB of text rendered. Above this point the text is there, but not rendered, if you delete a portion, you can see more text coming up. On the other hand, I realized it is should be enough for short notes. So, I have adapted the textarea and scrollbar to this behavior. The area you can scroll is the area rendered, below that point the text will be actually there, but not rendered in the game. Salud.
