Content Not Published when trying to post in the forum

Today I was going through my notifications and responding to posts as many do, when all of a sudden, this happens......

It is hard enough to keep track of where I am at in my notifications because when I look at them once, they ALL get marked as read. So when going back in it is a real pain to find where I left off. So this happening and saying try again later, when later I will probably have more notifications and then really have to spend some time to figure out where I was, is just terrible. Why would we be penalized for replying to existing posts we participate in? Maybe I could understand if we were limited to how many new posts we could start within a certain time frame but this is just bananas to me. 

I have posted before about the problem of all notifications being marked as read when you go into them. If that was fixed this wouldn't be such a big deal. Not to mention it would be time savingly awesome.
