Electric Bow requiring arrows

[nop277]

I just made the electric bow but noticed it won't fire on its own but does require arrows despite what i see in the tutorials to it. I figured out finally the firing mode, which got switched to shift + M instead of shift + right click (which made no sense since that is the same as crouch firing). Anyways the only difference that makes though is it makes the arrow flaming, but still doesn't allow me to just fire an arrow without requiring an arrow. I also noticed that the energy cost is significantly lower than the 1.2kj per shot. I've experienced other things like this that ended up being intentional (like the lack of gui on coal generators and battery boxes) and I was wondering if this was one of those changes or a bug i am experiencing
