(NOT A BUG) Dogmens

[Ruler]

Even I can't tell what really happened because nothing didn't but I was playing Sitting Bull and I was able to make Dogmens without copper. Spearmen and Dogmens both need copper I could build Dogmens but I didn't had copper for Spearmen. I didn't get any message of any sort.

Dog Soldiers require bronze working to build, but that doesn't mean they need copper - they are actually a resourceless unit.
