You are no programmer then, Changing one thing can have infnite effects on the rest of the system that take time to check and perfect. This is why even the most perfected programs still have bugs and problems, because human mind is the one doing the checking, there is no guarantee you check and fix every error that has passed. With people up bungies throat 24/7 and them practically being forced to get this stuff out soon as possible its no wonder they have bugs in the updates that need to be fixed, And the fact that the game has to be taken down for maintenance for every fix. So they can only do this once a week or then the playerbase will whine about the game being down. So practically either you are a carbage programmer, or not programmer at all.
