Save on Send does not load on v1.94 with esp8266

Hi,
I don't seem to be able to load with Save on Send of the web ide. save() works and load correctly, but with setBootCode looks like the load does not load anything. Sometimes it triggers "ERROR: Prompt not detected - upload failed. Trying to recover...".
For me, Save-on-send didn't work either on the v1.93, I get "Not connected to the internet", with and without load-as-function option (see http://forum.espruino.com/conversations/­296431/). Until now, the only way to get this option working is with v1.93.162 I compiled (http://forum.espruino.com/conversations/­305014/#comment13761399).

Here is my code :

function start(){
pin=NodeMCU.D2;
var dht22 = require("DHT22").connect(pin);
var dht22_read_test = function() {
  dht22.read(
    function(a){
      console.log("Temp is "+a.temp.toString()+ "C and RH is "+a.rh.toString()+"%");
       
     });
};
setInterval(dht22_read_test,3000);
print("started");
};

E.on("init",start);
print("init");

Here is the result with v1.94 :
