How to use Mod checker?

A DayZ server that crashes on startup or refuses players often has an inconsistent mod list: a duplicate, a dependency loaded too late, or a mod missing on the client. The mod checker analyzes these cases in seconds.

Paste your -mod=@A;@B… parameter (or a list, one Workshop link/ID per line) into “Server mods”.
Optional: paste the affected player's list to detect what is missing or extra.
Read the report: duplicates, load order, server/player differences.
Copy the normalized line (duplicates removed) into your launch script.
For mods given with a Workshop ID, copy the SteamCMD command to download them (appid 221100).
