That was the most technical and expressive way I could think to put it!
Normally when I enter a thread, then click the back button when I've finished reading, it returns me to where I had scrolled to last. At the moment it seems to be taking me to a random place on the page, and quite often refreshing the topic list all together.
Not a huge issue in the grand scheme of things but pretty annoying since I quite often look at the list of active topics and think "I'll read this one now and that one next" so to find it gone when I return is irritating!
I'm on the mobile site, using chrome for android if that helps at all.
