Are they supposed to shoot flames?

Well you got a motor for free from CC and a loaner MMM from me so not all bad - this was always a risk... I've had three MM's die flaming deaths...

A couple of failures rained molten fets onto my Lipos and burnt holes through HS and plastic wrap right up to lipo sheath...

Tough luck never the same... Look on the bright side you now have a 4s lipo which is perfect for a 1Y and you won't have to wait 2 months for a v3.
