I (playing as Celts) was sharing a continent with the japanese and the romans. I noticed that the japanese were in control of a massive amount of ivory. The only other ivory was a single tile located somewhat outside of my core but since i like the SOZ and did not want the japanese to get it I decided to found a city there anyway and connect the ivory. Meanwhile i set my research path in the direction of the required tech for the SOZ and started the Oracle as a prebuild.
That all worked perfectly, i founded a town, connected the ivory and was able to switch to SOZ and finish it.
So now the strange phenomenon occurs that I did not know the wheel nor horsebackriding but was able to build mounted units
.
I think this is strange, ok building the SOZ requires ivory, but are the horses also made out of ivory? I think the ability to generate the ancient cavalry should also require access to horses.
