Light junk blacksmith upgrades inconsistent

The light junk description says that this ship benefits from blacksmith upgrades. However, range defense +1 does not give any ranged defense. In contrast, +1 ranged attack does work. This was tested with the Mongols, but I’m guessing this is the case for all civs that share this ship.

Thanks @RNjesus2718! I’ll get this logged so we can track it internally. Appreciate it!
