For the academy buildings, here is the code:

academy requires factions { romans_brutii, egypt, romans_scipii, carthage, parthia, numidia, thrace, greek_cities, macedon, romans_julii, seleucid, britons, gauls, scythia, saba, } and building_present_min_level market market and building_present_min_level government gov4

scriptorium requires factions { romans_brutii, egypt, romans_scipii, carthage, parthia, numidia, thrace, greek_cities, macedon, romans_julii, seleucid, britons, gauls, scythia, saba, } and building_present_min_level market forum and building_present_min_level government gov3

ludus_magnus requires factions { romans_brutii, egypt, romans_scipii, carthage, parthia, numidia, thrace, greek_cities, macedon, romans_julii, seleucid, britons, gauls, scythia, } and building_present_min_level market great_forum and building_present_min_level government gov2

We don't really have control over anything else that could be getting in the way. You sure you have a forum level market there?

The heliopolis thing is a bug, but we are about to redo all unique buildings, so it will be solved in the near future.

---------------------
Mak, Epeirote, and KH generals all share the same skin currently. The first two just aren't done yet.

Koinon FM can be taken out of phalanx if you group him with another phalanx unit and then click the button. Long term plans are for a new unit that won't have phalanx option for the FM, so this is just a temporary issue.

We will probably be taking the somatophylakes strategou unit out of custom battles, but the change to epilektoi was a late one, so it just has to wait a bit longer.

Prom didn't release barbarian cities for RG yet that we are aware of.

We will look into the Illyrian unit problem and the spear length issue.
