dredknightHello cohopx,
I have never seen this problem, perhaps Koipse suggestion can help.
Koipse,
Racial skills are gone as they were either to overpowered or too weak. They were either removed or adjusted and inserted as perks in specific trees.
I do not understand your other question about "addition of units" can you explain it a bit better? Probably I cannot translate it very well.
Greetings,
Ok, i understand now 
Thank you about skills explain.
About "units" i mean NCF creatures.
