Mobx warnings in release UI bundle.

[Idorobots]

[mobx] you are running a minified build, but 'process.env.NODE_ENV' was not set to 'production' in your bundler. This results in an unnecessarily large and slow bundle [main.js:1:62764](http://192.168.1.96/static/main.js)
[mobx] `observableArray.sort()` will not update the array in place. Use `observableArray.slice().sort()` to suppress this warning and perform the operation on a copy, or `observableArray.replace(observableArray.slice().sort())` to sort & update in place [main.js:1:45556](http://192.168.1.96/static/main.js)
