For the past three or four days, whenever I read a topic that is marked as "new", the topic directly above that in my list which is also "new" loses that marking. It's as though the forum software is marking all threads around the one that I read as "having been read". Sometimes, if I'm reading a topic for a while, it randomly assigns "new" statuses to threads. This is making it kind of difficult to keep track of what I have read.
Any known issues?
