I think I've tracked this one down. In the Factions_GDI.xml file (and Nod, too), the PawnGroupMakers entry for Trader specifies Tiffalo_TBI as carriers. However, at the end of the definition of biomes (in Biomes_Temperate.xml, for instance), there is a list of allowedPackAnimals, which seems to determine which pack animals an incoming trade caravan can use. Since Tiffalo aren't in that list for all the biomes in the core game, the game fails to create the caravan since it can't find any valid pack animals.

I've worked around it for the moment by adding a patch file with the following contents:

<?xml version="1.0" encoding="utf-8" ?>
<Patch>

<Operation Class="PatchOperationAdd">
<success>Always</success>
<xpath>/Defs/BiomeDef[defName="TemperateForest"]/allowedPackAnimals</xpath>
<value>
<li>Tiffalo_TBI</li>
</value>
<order>Append</order>
</Operation>

</Patch>

This only works for Temperate Forest, though. There may be a general-purpose variation of this that works for all biomes, but I haven't gotten that far yet.
