Units that can't recruitable in the Campaign

[Seduce]

Okay I tested this, and these are the units from each faction that can't be recruited in the campaign
Empire of Altdorf: Reiksguard, Reiksguard Foot
Empire of Middenheim: Teutogen Guard
Vampire Counts: Wraiths


So far, these are the only ones I tested that can't be recruited in any way.

OK, try this patch file, which should add the Imperial units to top level palaces and the Wraiths to the high levels of the Von Carstein and Lahmian building trees. Just paste it over the current one in WHTW/data.
