Saving Wifi Config Foobars Everything

I am running espruino 1v95.173 on a NODEMCU board.

I can connect to a WiFi AP like this (Per the docs)...

var wifi = require("Wifi");
wifi.connect("my-ssid", {password:"my-pwd"}, function(err){
  console.log("connected? err=", err, "info=", wifi.getIP());
});
wifi.stopAP();

However the moment I add wifi.save() and reboot, the 8266 gets stuck in what looks like a reboot loop and barfs all over the screen. This forces me to reflash...
