I had a vaguely similar experience. I was working on virtual reality race car simulators that used sophisticated custom designed and built motion platforms. I had several responsibilities, the first was the software that controlled the motion platform. When it was done, and I proceeded to the sound effects system, my boss turned over my motion platform code to his good friend who he had brought on to the project with no interviews. A month later in a status meeting, the new guy said that he had to replace about 20% of my code to fix defects. I was curious, looked, and saw that there were zero code changes, but the comment blocks were changed replacing my name with his. Kind of sad for him. He literally had done no work.
