Launcher 0.102 replaces dead-end setup errors with a recovery guide. Prepare server files is always the main action. If other files conflict with the collection, the launcher shows you exactly which ones before setting them aside, keeps numbered backups, and can put them back.
When mods are missing or out of date, it walks you through opening the collection, installing or updating in Vortex, deploying, closing Vortex and checking again. A Skyrim folder you pick by hand is now remembered between launches. If you chose a custom folder before this update, you may need to choose it once more.
Launcher 0.102.2 is the current version on both servers.
