Casualties Unknown Troubleshooting

The fixed test order

1. Launch unmodded. If it fails, the problem is the game, the store install or the platform.
2. Verify game files through the store client.
3. Reinstall the loader. Launch once and confirm the log.
4. Add one mod. Launch again.
5. Read the log before changing anything else.

This order is boring on purpose. It turns a vague failure into a single suspect.

Black screen or instant close

• Confirm the unmodded game still launches.
• Remove the plugins folder and test the loader alone.
• Check the game's own log and the loader log for the last line before exit.
• Verify game files through the store client.
• If it only fails with mods, add them back one at a time.

A black screen with mods installed is usually a loader or plugin failure, not a graphics problem.

Mods not loading

Open the loader log and search for the mod name. If it is absent, the loader did not see the file. Check the folder, the file extension and whether the mod is a plugin or a file replacement.

If it appears but fails, read the error line: it usually names a missing dependency or a version mismatch.

Version mismatch after an update

The game updated and the mod did not. Options, in order of preference:

1. Update the mod or loader to a build that supports the new game version.
2. Roll back the game to the supported build if the store allows it and you accept the trade-off.
3. Play unmodded until the mod catches up.

Do not force an old plugin into a new build and then report a crash as a game bug.

Collect evidence before asking for help

• Game build or version string.
• Loader version.
• Mod list with exact versions.
• The last 20 lines of the loader log.
• What changed since the last working launch.

With those five items, most problems are diagnosable in one reply. Without them, everyone guesses.
