Topic: OK to ignore failing test

I've been having a strange problem all afternoon. In one of my integration tests, I'm getting a routing error, where Rails isn't able to resolve a URL given as a redirect from one of my controller actions. However, the test gets the exact same URL earlier in the test, and it resolves fine.

Also, when I manually perform the action using my web browser, it also works fine.

My question is, then, is it OK to ignore the failing test? Or am I likely to see errors in production later on?
