Broken Abilities
One of the two abilities doesn't show up in the Human unit.
Ability 1: Drag Ability 2: DragRAGE
Ability 1 does not show up, while ability 2 does. They are both completely identical as far as I know and I can't find anything in the map that would disable the Drag ability, I searched through all of my XML data and couldn't find anything that would point to that, and the word "Drag" isn't even in my trigger editor.
There is a engine limit of 32 combined abilities across all morphs that a unit has. You'll need to either remove abilities or remove morphs and handle this differently until the game can support a greater number of abilities.
