I caught that too. You have a lot of small mistakes in your technology prerequisites. Here's the list of what I caught:
- Advanced Computers: Nanogenerators is not appearing (replace NANOGENERATORS with NANOGENERATOR)
- Affective Algorithms: Automated Traffic is not appearing (replace AUTOMATEDTRAFFIC with AUTOMATED_TRAFFIC)
- Asymmetrical Architecture: Mesh Networks is not appearing (replace MESHNETWORKS with MESH_NETWORKS)
- Biomimetics: Asymmetrical Architecture is not appearing (replace ASYMMETRICALARCHITECTURE with ASYMETRICALARCHITECTURE)
- Bionics: Exocortex Networks in not appearing (replace EXOCORTEXNETWORK with EXOCORTEXNETWORKS)
- Cloud Computing: Modern Warfare is not appearing (replace MODERNWARFARE with MODERN_WARFARE)
- Conglomerates: Derivatives is not appearing (replace DERITATIVES with DERIVATIVES)

- Graphene: Controlled Plasma is not appearing (replace CONTROLLEDPLASMA with CONTROLLED_PLASMA)
- Holographics: Evolutionary Algorithms is not appearing (replace EVOLUTIONARYALGORITHMS with TECH_EVOLUTIONARYALGORITHMS)
- Invisibility: Nanogenerators is not appearing (replace NANOGERATORS with NANOGENERATOR)
- Machine Binaurals: Replacement Organs is not appearing (replace REPLACEMENTORGANS with REPLACEMENT_ORGANS)
- Machine Learning: Neurotechnology is not appearing (replace NUEROTECHNOLOGY with NEUROTECHNOLOGY)
- Media Psychology: 3D Printing is not appearing (replace 3DPRINTING with 3D_PRINTING) and Communication Networks is not appearing (replace COMMUNICATIONNETWORKS with COMMUNICATION_NETWORKS)
- Modular Armament: Military Robotics is not appearing (replace MILITARYROBOTICS with MILITARYROBOTS)
- Neurotechnology: Virtual Reality is not appearing (replace VIRTUALREALITY with VIRTUAL_REALITY)
- Photorealism: Virtual Reality is not appearing (replace VIRTUALREALITY with VIRTUAL_REALITY)
- Rapid Recuperation: Gene Enhancement is not appearing (replace GENE_ENHANCEMENT with GENEENHANCEMENT) and Mesh Networks is not appearing (replace MESH_NETOWRKS with MESH_NETWORKS)
- Romanticism: Chivalry is not appearing (replace CHIVARLY with CHIVALRY)
- Skyroads: Animilia Exoskeletons is not appearing (replace ANIMILIAEXOSKELETON with ANIMILIAEXOSKELETONS) and Nanogenerators is not appearing (replace NANOGENERATOR with NANOGENERATORS)
- Speech Recognition: Wearable Computers is not appearing (replace WEARABLECOMPUTERS with WEARABLE_ELECTRONICS)

- Universal Translator: Animilia Exoskeletons is not appearing (replace ANIMILIAEXOSKELTONS with ANIMILIAEXOSKELETONS)
- Wireless Electricity: Nanogenerators is not appearing (replace NANOGERATOR with NANOGENERATOR)
This is what was on
Koshling's list that was not on mine:
- Hypersonic Flight: TAEM Simulation is not appearing (replace TAEMSIMULATION with TECH_TAEMSIMULATION)
- Replacement Organs: Rapid Prototyping is not appearing (replace RAPIDPROTOTYPING with RAPID_PROTOTYPING)
I don't think there is an easy way to avoid this. It looks to me that what Civ4 does with bad XML prerequisites is to just skip them and move on without any kind of message. What I do when I add anything is to immediately go into the game and make sure it matches what I intended. I usually check the Civilopedia first and then try to build whatever I was trying to create. WorldBuilder is a huge asset, but I notice crashes happen when I have no rival civilizations (which I can do with Mastery Victory and like to use for testing).
