Model 3 software and battery issues

In an article by Fortune Magazine ( http://fortune.com/2017/11/01/tesla-elon-musk-model-3-earnings/ ), Tesla is having a supplier issue related to its battery assembly robots that has caused Tesla to have to re-write all its factory build battery software from scratch, delaying production. Elon Musk is sleeping at the factory while the issues are being resolved. Note again: this is not a problem with the Panasonic batteries or supply, it's the assembly robot sub-contractor that dropped the ball, forcing Tesla to take over that portion of the build (and building Model 3 battery packs by hand).
