I'll check which items, I wanted to mention before I forget, sometimes when the centaurs die, they have female death sounds even though the units are all males.
Items without weight (Some of these are vanilla I think):
Humming Bird Pike
Spectral Chain Shirt
Sacrificial Dagger (Pretty sure this one is vanilla)
There were a few more that were on the guy that went to Avalon, but I have been autosaving.
I apologize in advance if the above items are all vanilla.
Is there a way to play these factions with the vanilla factions? Also, do you know if there is a hard limit (Besides map spacing and such) to the total number of factions you can have on a map?
