Apologies if this topic has already been covered, a quick search didn't reveal anything so I made my own thread. I created three new units: a dog, a kennel to produce the dog, and a builder to produce the kennel. I created the dog, gave it a weapon, customized it and ended up with a finished product that was exactly what I had in mind. I made the kennel, made the trigger to produce the dog, and everything was fine. I went to make the builder, and now things are starting to get purely bizzare. I created a custom "Build" ability for him, made the Button for the Kennel, and whatnot. The Build ability has a name, and an editor prefix, and when I go onto the "Abilities" list it is there, staring at me in the face. However when I go to add the ability to the unit, it is simply not there on the dropdown menu. This has also happened with an Effect, where I could not add the damage effect to a weapon I had created. Has anyone seen this problem, and does anyone know of any solutions? It could be a simple field in the data editor, but the magnitude of the editor is quite substantial, so it's hard to find exactly what you want if you don't know what you're looking for. Thanks for any assistance you can provide.
