Callum, sorry to not respond sooner. I somehow overlooked your posts to this thread the last few times I've been on the forums.
That's a very puzzling set of symptoms, especially since we haven't made any recent changes in those areas, and our automated error logging hasn't reported anything. Are you seeing this behavior with all your characters? Also, do you remember when you were last able to play without problems?
Chrome is usually a pretty well-behaved browser, but it's possible that particular version has a glitch on Android. Updating to a newer version -- I think Chrome 37 is out -- might be worth a shot. If you haven't tried logging out and clearing your browser cache, that would also be worth trying. We've seen a few cases in the past where mobile browsers cached bad data when there was a connection hiccup.
Let me know if any of that helps. In the meantime, I'll continue digging into the problem.
