Whats Changed
Additions
- Added a "Fix NXM Handler…" button to Settings (General) to re-register the nxm:// protocol handler on demand, if Nexus's "Download with Manager" ever opens the wrong app or does nothing
Bug Fixes
- Fixed "Download with Manager" on Nexus sometimes opening a brand-new Mosaic window instead of using the one already running. Closing any duplicate/stray Mosaic window could silently delete the running instance's download-handoff channel, so the next Nexus download had nowhere to go. Mosaic now enforces a true single-instance lock — only one window can ever be open at a time, and a second launch attempt (a Nexus download link, or just relaunching the app) is handed off to the existing window instead of opening a new one. This also closes a real (if rare) risk of two instances deploying or restoring mods for the same game at the same time
