The links that lead to the sites to vote for Combine do not disappear after you click on them. I gain the CP bonus but the links remain active. The active links don't give out CP though if it hasn't been 24 hours.

Do you guys know what the problem is here?

This is working fine for me on Firefox. It might be a problem with your browser.

I have Firefox as well and it only started just recently. I haven't made any changes Firefox or anything that would affect it.

You obviously need to refresh the page.

I'm not sure if that was a serious answer or not but either way, I hope its not the best answer I'm going to get here.

Unfortunately, as this does not seem to be reproduceable and I have seen no other reports of it so far, we may not be able to offer any solutions. If this problem persists you should post it in the bug base for one of the developers to take a look at when they have a moment.

Try clearing your cache then refreshing. That could help. FF has a cache behaviour which is sometimes tricky.
