Forum:Older "Recent Changes" are no longer showing

Is there something random about how far back "Recent Changes" goes? As far as I can tell, in the past 30 days my wiki has more than 50 changes but no more than 100. Yet even when I do http://warhawk.wikia.com/index.php?title=Special:RecentChanges&limit=500&days=180 nothing new shows. I know there are edits in the past few months. In fact, I know just a few days ago that very query did show me some old results, now it's not. Is something broken? (& yes, I cleared my browser cache) --Jason C.K. 18:51, September 16, 2009 (UTC)

I think Recent changes don't keep to many information or to old information-- 19:03, September 16, 2009 (UTC)

I'm pretty sure there is a 90 day max limit. --Uberfuzzy 20:39, September 16, 2009 (UTC)
 * A few days ago when I tried for a 180 day query, I know I was seeing stuff in April. Is the limit intermittent, based on site load?
