Ask in game
Type #csc help in chat. It lists every command you can use. #csc help <command> explains one of them.
Staff watch chat. The welcome screen says it too: staff can be reached with #csc help in chat.
Report a problem with a ticket
A ticket goes straight to staff and is saved on the server.
From the pause menu: pick Report a bug. Choose a category, describe what happened and press Send. You can choose to attach your game’s recent log lines. They help staff find bugs.
From chat:
#ticket <text>or#bug <text>sends a ticket. Write at least 10 characters.#csc ticket minelists your tickets.#csc ticket <id> reply <text>adds to one of your tickets.
When staff answer, you get a pop-up if you are online.
Good tickets say where (grid or base name), when and what you expected. The game adds your position and the server time for you.
AFK checks
When the server is busy it checks for idle players. You get a warning with a short code first. Answer it with #here <code> (or #afk <code>). If you do not answer, you are kicked to free the slot.
Discord
For anything that is not urgent, or to appeal a decision, use the server Discord.
