Maybe not regularly it was a wrong term more of it happens more then it should.
I believe money can indeed make a barrier of programers who can prevent this from happening or resolving issues at a much faster rate.
But your right whats done is done, and my argument isn't towards bashing Riot if it was I wouldn't be playing this game its to everyone who says this game is free and I should just "get over it"
Throwing money at things doesn't make people work better, and hiring more people would make things worse.
Imagine you were writing a book. Suddenly you get stumped, so you call in a friend, and ask for their advice, and you two work on it for a while, then find yourselves in a corner, and end up calling a third friend. Eventually you'll get to the point where all of the people who you've called have no idea what they are supposed to be working on, and the book becomes completely different from where it started out. Not only that, but your main characters, which you so lovingly crafted, are now nothing like what you wanted them to be.
That's kind of what you're proposing. Hiring more programmers makes MORE issues, because not only do they need to become fluent in the games code, they need to become fluent in each others code style so as to not produce issues like this. It is entirely possible that this issue arose because of a new programmer hire missing a single word in the massive string of code that is League of Legends, how is hiring more people who have no idea what they are supposed to be looking for going to help? How is throwing more money at the people who are already working their asses off to fix it going to help?
And for those who are all raging about my "non-paying customers" quip. I have put in a decent sum of money into this game, more than I would most other games, that's for sure, and I intend on doing so again when I can afford it.
