When using RCON to send SQL queries to a dedicated server, the server will crash under the following conditions.

  1. The query is a “select” statement
  2. The result of the query would contain at least one row where at least one of the columns has a null value

From server log:

Please provide a step-by-step process of how the bug can be reproduced. The more details you provide us with the easier it will be for us to find and fix the bug:

  1. Run a dedicated server with Rcon enabled
  2. Ensure there is at least one character created on the server that is not in a clan
  3. Connect to the server using an Rcon client (such as mcrcon 0.0.5)
  4. Run the following command from the connected Rcon client.
    sql select * from characters
  5. The server will crash and never respond to the Rcon client (because the guild and rank columns have null values)
