the c4 detonator in command room is linked to channel 0 instead of 999, and the one at the front of the ship is linked to chanel 99. as a result the sub has a habit of exploding when you try to send messages in chat using wifi components.
also the battery drains constantly, which im assuming is not supposed to happen. that can be fixed by running a wire from the reactor junction box into the battery relay power in

I'll take a look at the detonators. That's not supposed to happen since the battery is a toggle from nav, maybe you've accidentally had both the battery and reactor active.
