[b]Because that simply isn't how game development works.[/b] [b]They do not focus on fixing cheeses over bugs. [/b] Bugs may occur at any time, and for example the most recent ones (invisible comp players, spectator, loading times in strikes etc) happened AFTER the patch, how would they patch a bug out that doesnt exist yet? Bugs may require different ammounts of time and resources to fix. The Guitar Error in Last Wish for example was more than just a accidental line of code. It had more fundamental problems which needed to be addressed which of course takes longer and requires more investigation as to not cause even more issues. Bugs, exploits and glitches may have varying priority. Somthing that has an easy workaround may be put off to work on more immediate bugs that dont have workarounds which are causing more of a problem. It's also unfair to say they are patching exploits or cheeses over bugs, they simply aren't. But fixing them is integral to the game, things should play how they were designed to be played. It defeats the entire point if you could just cheese the entire game.
