Mismatch between 18xx module and 18AL extension

Am getting the following error message

  • Extension ‘18AL’ was built for module version 2.13. You are running version 2.12. It’s recommended you upgrade to the latest version of 18xx

I am fairly confident that I have downloaded, installed, and am running the most current version of both 18xx.mod and 18al.mdx. How can I get this working again?

This a warning message, not an error. It does not stop you from playing the extensions with module.

Chances are that the changes to the module will not affect the operation of the extension at all. Someone just needs to edit the extension and resave it using the newest version of the module.
