Latelly it happens to me to have notification of new messages on boards and when I go and check them out it just shows me messages I had already read.
For instance, as I'm writing this, Szirak's message has a "New!" symbol on it even though I had read it before. But when I read it the first time harley's and Szirak's previous messages were marked new as well and now it's just this last one so it can't be a cache issue.
This has been happening ever since new year and I think (but not sure) it has something to do with the fact that the messages in question were posted just about the time I was reading them.
The first time I just thought it was a fluke, with me having hit the board at almost the exact same time of the post. But it's happened 6 or 7 times in the last few days so now I start to think it's just too much of a coincidence...

Are you still doing experiences with time-travel Fencer? ;)
