@paradamed: thanks for reporting! The Seleucid chariot is unchanged from RTR and that's why you don't see them in the preview... All will be fixed in v2.6!
The camera thing is due to the default preferances I set (for close-look but not good for commanding!), if you have no existing preferences in RTW or RTR. You can set higher FOV (Field-Of-View) in the mod launcher - like 75, and change in game options to use "RTS Camera" instead of "Total War Camera".
