I just went through and fixed a bunch of stuff. I discovered that the original author of the Nagash mod is referencing vanilla units like this Main_Unit Key (Nagash custom name) but Land_unit Key = vanilla unit name. So if he references a vanilla unit like that, for his custom unit, it may not be present in the land unit tables for the Nagash mod, for instance there is a unit count discrepancy between Main_Unit_tables and Land_unit tables. The amount of line items is different meaning I may not have access to edit all the hit points of some units, ( Like ROR's or whatever else is missing from the land_units list)because his mod is referencing (using) vanilla unit lists.

I re-checked every:
-Infantry_Melee Unit
-Infantry_Missile Unit
-Commander Unit
-Monster Unit
-Chariot Unit
-Cavalry Unit
-War_Beast
-War_machine

I did find some commander/chariot units that weren't labeled as such, Like they were called Infantry_Melee instead, so when I filtered for them previously they were not found like normal. They are now fixed.I also fixed a bunch of Cavalry/Warmachine/Chariot Mount and Men counts, like for instance some Chariots had too many mounts/men vs. engine counts. This has been fixed. If you go through it and find something wrong, please list each unit you find by the Unit Name so I can check them. Either way you should see a huge improvement to the numbers and health and many units.

Thanks @Seki19 for reporting units that needed adjustments.

Updated Mortarch/Hero/Character hit points to be 200% of default values as intended.
