I changed the progress bar for the primary asset extraction and build process. It already had a maximum file count higher than the repository itself and even would assume a count of 1,000 less if it exceeded the maximum of 3,000 files one time, so it should have been highly unlikely for file count to exceed that assuming basic operation of the launcher and Zelda 3 software. There are always potential issues leading to duplication of files or people making manual backups not to mention the fact that this is essentially a wrapper for another project that can continue to expand its own file count as well, so exceeding the maximum value for the progress bar is rare but not unheard of.
I wanted the bar to be a better indicator of the actual progress of the process, but for the sake of a more reliable product, I have instead changed to a system where the bar simply updates with each subsequent step rather than based purely on the file count as before. It is not as granular as I would like, but without full control of the directory and the original project, this really is the best solution.
