The developers class bug fixes as new content, they said so when discussing the legacy edition that's supposed to be coming up at the end of the year.
I've always found it scummy when they release new content before fixing existing content, I wouldn't dream of allowing that if I was in charge, but then again quality isn't the top concern anymore. Moving forward without addressing existing problems makes things much, much harder to manage further down the road. The same studio left the third game in an appalling state and they will do the same to four if people don't make a fuss.
Yes, new updates will always mean new issues, but the sheer amount of issues that come through with some of them is ridiculous.
