Over the last week (or two, not quite sure when it started), I have been having issues where I will visit, use the New Posts link, and read some posts. Then I'll close the window/tab and come back anything from 5 minutes to multiple hours later, and either it'll remember what I've read, and show the New Posts accordingly, whilst at other times it'll revert to whatever time it has decided my last visited time is... For instance, today, I first visited ~8am, popping back in occasionally all day to this point (reading a few posts as they appear via the New Posts, each time displaying correctly from my last visit). For most of the day my "last visited time" is 11:45, and now its reverted back to showing me everything since that time... a) why isn't my Last visited time updating? b) why does this only sometimes impact the "New Posts"? Hope that makes sense! Suggestions? Is it just me?
