This is because the core was broken (due to debugging something else), so the bot had no score data; in that case the score is null or as far as IRC is concerned an empty string. This is expected as anything post-core is 0-1.

The format hasn't changed AFAIK, comments are not escaped, the format is as below:

I've updated the crontabs to restart the processes with no stdout/stderr logging enabled (https://github.com/DamianZaremba/cluebotng/commit/3d026466688691972563313a6f1f8720c3efe714) to ensure the /dev/null doesn't get reverted and re-deployed the code.

I've cleaned up the code in both bots and put in MonoLog with a daily rotation. I'll keep an eye on the size for a couple of days to make sure things are looking ok.

Thanks @chasemp! I can see the logs are current linked to /dev/null.

I replied to the mailing list about this, in reply to the email about NFS running out of space.
