Start with the argument setup in plugins/Bigfile/BigfilePlugin.py and plugins/BigFile/BigfilePlugin.py, then follow the Config.loadPlugins() call in src/Config.py. Compare where --autodownload_bigfile_size_limit is registered and reproduce the startup command shown in the report. Done means ZeroNet starts without the argparse conflict.
