I'm having a similar problem to others' I've read earlier, but their fix hasn't worked for me yet. I am running KSP 1.3.1, TCA 3.4.0, and AT_Utils 1.4.3. I see the modules in the tech tree, but I don't see any TCA menu in the VAB or in-flight. Am I on the wrong versions of anything? Or missing something silly and obvious?
