Waterloo Module outdated custom code


I am trying to play the Waterloo module from Avalon Hill, but have gotten the message about outdated custom code. The last time it was updated was in 2011, so I imagine the author is not active. Is there something I can do to update this myself?

Firstly, if the module plays without generating any crashes, you can ignore the warnings and use it. Not ideal, but it will work. (In this case I have checked and the module is usable).

It is still worth trying to contact the module maintainers, many old hands are still around.

If that doesn’t work, report back here and we will see what we can do.
