Since Patch 19.2, the guild roster has been glitched (again, since this isn't the first time this exact glitch has been introduced by an update). Players can no longer scroll through the roster without it resetting your view to the top, every time any change in the roster occurs. So, if a player in the roster travels from one location to another, that's a change and BAM! Your viewing position is reset to the top of the roster list. Trying to scroll through your entire roster to check/update member notes for things like weekly dues dates (trading guild thing)? Good luck! You might make it 30 names down the list or, just 3 names down the list before something changes (someone comes online, travels, goes off line) and BAM! Back to the top of the list.
