  • Specify the platform (Windows, Linux, OSX) and your OS version.
  • Provide a detailed account of the problem.
  • If the bug relates to ZScript, please supply the script, and/or a quest file.
  • Please do not submit reports for ancient/old beta versions of ZC, unless the bug persists in the latest 'final' release.
