The installer makes a verified rollback backup and directly patches the already-subscribed Workshop VPKs, so no second map subscription or Workshop Tools mode is needed. It refuses unknown map versions. Uninstall.cmd restores the verified original Workshop files; Diagnostics.cmd creates a support ZIP for Issue reports.
Installation is normally one-time. The launcher checks hashes on each run and only reapplies the selected edition if Steam restored the exact supported original Workshop files.
For a reproducible problem, run Diagnostics.cmd in the extracted package and open a new Issue with the generated ZIP, a screenshot if relevant, and the action that triggered it.
