Confusing changes to code made by save() - dump()

Hi
Love the Espruino. Having loads of fun seeing what it can do. However have issue that is confusing me. Can somone help.

I wrote the following code...

var list = [
      {"b":0,"g":0,"r":0,"s":0},
      {"b":0,"g":0,"r":1,"s":45},
      {"b":0,"g":1,"r":0,"s":90},
      {"b":0,"g":1,"r":1,"s":135},
      {"b":1,"g":0,"r":0,"s":180},
      {"b":1,"g":0,"r":1,"s":120},
      {"b":1,"g":1,"r":0,"s":90},
      {"b":1,"g":1,"r":1,"s":60}
    ];
var MIN_SERVO = 0.63;
var MAX_SERVO = 2.34;
var ONE_DEG = (MAX_SERVO - MIN_SERVO) / 180;
var ZERO_DEG = MIN_SERVO;
var step = 0;

function posServo(deg) {
  return E.clip(MIN_SERVO + (ONE_DEG * deg), MIN_SERVO, MAX_SERVO);
}

var servoPos = posServo(0);

function stopTimer() {
  if (timer) {
    clearInterval(timer);
    timer = undefined;
  }
}

function nextLights() {
  digitalWrite(LED1, list[step].r);
  digitalWrite(LED2, list[step].g);
  digitalWrite(LED3, list[step].b);
  servoPos = posServo(list[step].s);
  step = (step +1) % list.length;
}

var timer = setInterval(nextLights, 500);

setWatch(function() {
  stopTimer();
  nextLights();
}, BTN1, {"repeat":true,"edge":"rising","debounce":10});

var sp = setInterval("digitalPulse(C5,1,servoPos)", 20);

This works fine, my lights blink, my servo moves...
When I save() and reset the code does not start! However if I press the button it does get to the setWatch function and the device works from there.
If I do a dump() however there are some confusing changes to the code.

var list = [
      {"b":0,"g":0,"r":0,"s":0},
      {"b":0,"g":0,"r":1,"s":45},
      {"b":0,"g":1,"r":0,"s":90},
      {"b":0,"g":1,"r":1,"s":135},
      {"b":1,"g":0,"r":0,"s":180},
      {"b":1,"g":0,"r":1,"s":120},
      {"b":1,"g":1,"r":0,"s":90},
      {"b":1,"g":1,"r":1,"s":60}
    ];
var MIN_SERVO = 0.63;
var MAX_SERVO = 2.34;
var ONE_DEG = 0.0095;
var ZERO_DEG = MIN_SERVO;
var step = 5;
function posServo(deg) {
  return E.clip(MIN_SERVO + (ONE_DEG * deg), MIN_SERVO, MAX_SERVO);
}
var servoPos = 2.34;
function stopTimer() {
  if (timer) {
    clearInterval(timer);
    timer = undefined;
  }
}
function nextLights() {
  digitalWrite(LED1, list[step].r);
  digitalWrite(LED2, list[step].g);
  digitalWrite(LED3, list[step].b);
  servoPos = posServo(list[step].s);
  step = (step +1) % list.length;
}
var timervar sp = 2;
setInterval("digitalPulse(C5,1,servoPos)", 19.99950408935546875);
setWatch(function () {
  stopTimer();
  nextLights();
}, "B12", { repeat:true, edge:'rising' });
digitalWrite(A15,1);
digitalWrite(C5,0);

var step is set to 5, somtimes 7... never 0;
var servoPos = 2.34. However if I run from console I get the following:

posServo(0)
=0.63

also the line

var timer = setInterval(nextLights, 500);

is re-written as:

var timervar sp = 2;
setInterval("digitalPulse(C5,1,servoPos)", 19.99950408935546875);

and the var timer is not set and timervar is introduced. This is a mix of

var timer = setInterval(nextLights, 500);

and

var sp = setInterval("digitalPulse(C5,1,servoPos)", 20);

Finally the setWatch parameters are missing the "debounce":10

I updated to 1v67.. Read some entries in the forum and downgraded to 1v66 but it still does not work.

When I received Espruino I updated straight away and did not see and evidence of this. that was about a week ago. however in my excitement I did not note which version it upgraded to.

Currently it works from ram not from flash. If I reset() in the console(), press the reset button, disconnect battery and re-connect or load() in the console it does NOT run.

It tried minification on and off. It still does not work...

Can you please help...
