Welcome to the org!

concerning the missing client rulers see this thread

and the phalanxes:
If you build a gov4 and build a barrack (native or factional) it becomes a "gov4-barrack", meaning you can only train the allowed units. If you destroy the gav-type and replace it with another, the barracks do not change. If you want to get your phalanxes build new barracks after the new gov-type.

PS: Recruitment viewer:
the data is outdated, IIRC it is from 1.1, so be careful
