- Fixed pump had no wire in the depth charge compartment.
- Fixed bots getting stuck trying to repair drone walls (just removed the walls, they were needed to specify the drone dimensions and hitbox, although just hulls is enough).

- Fixed sprite depth for drone charging indicator.

- Bots no longer close ballast hatches.
- Minor sprite depth fixes.

- Fixed min voltage for the engine to 0.5.
(Accidentally it was set to 0 and the engine ran without power even when turned off).

@updated
- Increased total battery capacity and recharge rate by 60% (up to 32000)
- Reactor power is also equated to the batteries capacity.
- Reduced engine consumption by a third.

- increased engine power from 300 to 450. Now it's not so slow (22 km/h).

Fixed size and positioning for labels.
