As explained on the actual mod pages, there's been some problems. here's a copy paste:

"XIIICaesar, the previous "manager" of the Caesar's legions mod removed his mod. Problem is that my shield reskins require that. Until I get the energy and time to do it (some time in the future if not next year), I'll upload my copies of his mods#

Currently the only way that you can play with my reskins and the legions is to play the Ancient Empires mod of Attila"

i cant see any of the peopel in all your mods

Weird indeed - you sometimes even see "IIII" in stead of "IV" on clocks too!

I researched it and you're rigth. thoug its weird, I supouse that the numbering at the time was different. thanks for the feedback one learns new things everyday.

incorrect in the case of the imperal army, they did their 4s differently on purpose, can't remember why. Scythica tended to switch around between IV and IIII at different periods in history though.

an accuracy issue, a 4 in roman numbers is IV not IIII
