This is because Steam checks the integrity of the files after they are patched, triggering Steam to replace the files with the original, which again gets patched, and then fails the integrity check again.
I remedied this by adding a 5 second delay to the auto scanner, which has solved the issue on my machine but I think it might still happen for others. I need to figure out a more reliable solution for this.
