Chatpgt cannot follow memory saved instructions

Is it just me or when I give specific instructions to Chatgpt and update them to its memory it just fails to follow some of them? And that too repeatedly even after reminding it not to do so. And the funny thing is I’ve noticed that up until a few weeks ago it was able to follow every instruction perfectly and now it just isn’t able to do so. Eg. if I want Chatgpt to give me a 10 paragraph response each time I talk to it in one sitting like for creative writing, it’ll give me 8 or 9 now when earlier it would give like 12 or 13.
