I think most people whining about jagex not reimbursing items lost to bugs dont realize that your character and items ALL BELONG TO JAGEX and they really dont have to give them to you if you lost them. Personally, i wait at least a few hours after an update before i use runescape and therefore havent noticed a single bug other than graphical glitches (and mobilising armies missing 3/4 of the game modes.) Jagex does a great job of fixing bugs after they show up, and as for more bugs with projects with longer development times recently, thats because runescape is more complex than ever before, and more content will interact weirdly with other parts of runescape. Many more bugs only happen when content is used by many players simultaneously, as others have said earlier.
