I'm very impressed with the GTW mod, despite the outcomes.
I've had problems with two GTW Mods.
The first one is the "Azerothien Pikeman." A glitch detaches the weapon from the soldier and generically puts it anywhere. Perhaps you could fix/rebuild this unit?
Also, I couldn't find the TrollArmsHut.mdx anywhere inside the Resource Pack or on the map "SnapshotMap." Do you have this model, or does someone else?
