The mod Battery Powered (1.3.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event battery-powered::on_init()
battery-powered/control.lua:51: attempt to index field 'jetpack' (a nil value)
stack traceback:
battery-powered/control.lua:51: in function 'register_jetpack_fuels'
battery-powered/control.lua:58: in function <battery-powered/control.lua:56>

The code that added Jetpack fuels forgot to check if the Jetpack mod is actually enabled. This is now fixed with the new API in Jetpack because the Jetpack mod now requests fuels from this mod.
