You have customers complaining about everything all the time (and non-customers with a high profile "edgy" title like GTA), so filtering out the actually relevant topics might be hard (esp things like "bad loading time" when it might be the users computer). The thing is that this loading time issue probably didn't exist at release as it was part of something that got expanded on over time and only got bad worse by the years. Assuming somewhat linear growth of the data the loading time would have been at least 4x shorter only half the games lifetime ago (3 years) and 16x shorter 1.5 years after release. After that period they would probably not consider there to be issues in those places in the code so nobody really looked or realized anything was amiss there.
