EXPECTED RESULT auto-rebuild/recommence proxy at new settings SOFTWARE/OS VERSIONS Windows: 10 Pro | 19045.5854 intel i9-14900k ADDITIONAL INFORMATION VoD of the issue in question attached again, this can be worked around by simply letting the proxy be built fully, and then swapping to the new project settings, at which new proxies will be built
