Hey mate!
Think you forgot to put the link to the scripts :)
Either way, sounds like it might be a problem with crontab (scheduled jobs)
Been interested in working on more game-related projects so this sounds exciting!
I've got years experience of web development, done a couple server-sided browser-based games but nothing extensive.
I assume the budget is just for the small fix, yeah?
Looking forward to working with you!
