Until just recently there was a bug in (both of) the Custom Library Messages extensions that caused games to behave like that (see [url]https://intfiction.org/t/if-archive-hugo-downloads/59/1]). If you were using one of them, that may be the issue.
Ron Newcomb promptly fixed the bug, so if that’s what messed up things for you, you should only have to install the updated version of his extension.
