[Microbit-Python] error code?... :(020

Error code update.
I'm consistently getting the ":( 020" code after 42 button presses (of any combination of buttons A and B).
Is there a button click buffer that's overflowing somewhere? If there is I can't see a method on the microbit API to clear it.
Cheers,
Alan

Subject: [Microbit-Python] error code?... :(020
Hi,
I wrote a small program to draw on the LED matrix, but after setting a few LEDs on I get what looks like an error message on the LEDs:
":(020"
(Frowny-face zero two zero)
It just keeps repeating that and my program stops but there's no stack trace on the python repl.
Is that a built in hardware error code or something? Has anyone else seen that?
Here's my program:
====8<====
from microbit import *
index = 0
while True:
if button_a.is_pressed():
x = index % 5
y = int(index / 5)
display.image.set_pixel_value(x,y, not(display.image.get_pixel_value(x,y)))
if button_b.is_pressed():
index = (index + 1) % 25
