What should I do?
Ok, I did add the units to the EDU for the faction, did add the recruiting in EDB and also the UI unit info and unit... BUT it asks for some kind of crew from the model unit/textures and I don't want to mess that part up not knowingly what I am doing.
By "it asks" I mean I get an error when I fight with them, but I can recruit them. The error says that in model unit/texture it does not find the crew (tga file) for the chariots.
