When I started up an Axum game I noticed when I looked through the building browser there is no unique unit in the tier 5 barracks but there's still those stringent requirements on religion to get that barracks, there doesn't seem to be much point, is this actually the case?

Also a small bug report if you start as Axum you'll find in your unit recruitment section a unit that has no name, it's some sort of slinger but it doesn't say arabian slinger or anything, just blank where the name should be
