There's different levels of fixes
- CMS fixes, which don't require a new build of the game to roll out on both PS and PC at the same time
- Client fixes, which require a new build, which then needs to be QA'ed, submitted, and then pass through Sony's testing
- Server fixes, which don't require a new build, but are bigger than CMS fixes
CMS fixes include things like: Renaming a costume, swapping a costume in the store if it was missed off or incorrectly featured, changing the featured show, changing the newsfeed, etc...
Client fixes are anything that happens within the game itself, on your local computer - so this includes changing geometry in levels, changing artwork, changing costumes, fixing UI bugs, fixing gameplay bugs, physics... etc...
The HH bug is a CMS bug, which meant it was one of the more easily fixed ones.
When you talk about bugs that have been around for a long time - they're much more complicated. If there was a bug that was super negatively received, and easy to fix, we'd fix it quickly.
We've done many CMS fixes on weekends before - for example - sometimes when we've done featured costumes, they've been called "placeholder" and we've had to quickly update the CMS to change their name to what it's supposed to be. It's a low-risk fix that doesn't require a new build, so it gets done quickly.
