And all this in supposedly dogshit code that I can only imagine makes the simplest thing into a herculean task.
The fact that it's apparently hard enough to make a rerun of something because of shitty old code is one thing, but you can't really expect them to make NEW content to give them time to catch up when they're already behind on making other new content.
