This is a huge mess of spaghetti code with tons of global and common variables scattered throughout, as well as state being passed around in files. Dominique, please reduce this to the smallest amount of reproducible code, so we can attack this. Avoid reading and writing to files (as I see, these have only a minimal amount of data anyhow), and global variables if at all possible. Please only keep the code that is relevant to reproduce the problem.
