React Packager "Unexpected raw mappings" in 0.43.0-rc.2

Description

After starting Perf Monitor with Dev settings off, React Packager eventually choked without me doing anything with:

 ERROR  Unexpected raw mappings for G:\mobile\cadastro\lib\root.js
{"name":"Invariant Violation","framesToPop":1}

I think I found a way around this issue, at least for my setup. From the development menu on my android I selected Dev Settings and re-enabled JS Dev Mode that resolved this issue for me.

I am getting this as well. So on DEV mode ON, chrome debugging works the first time. Upon reload, the app is just a white screen. So I have to turn off Remote JS Debugging in order to get the app back again. Rinse and repeat cycle. 😕

"react-native": "0.44.0" I am using "react-native-navigation": "^1.1.81" though. Not sure if this has something to do with it.
