To add to this, when you have single paragraph events unchecked, I've found that you can add this little thing at the end of your action -> (extend the response to # paragraphs) <- swapping out # for a number to set the explicit length of the response the AI will return to you, and it will generally override any world/system prompts trying to manage response length for that single response. (this may also be used to temporarily correct the AI if it seems to return shorter and shorter responses in general)
Different length responses may have quite varied results as well - 3 or less usually leaves too little room for the AI to actually let anything happen, while 6-7 seems just about enough to have one or two significant things happen. 12+ tends be prone to jank though, unless you also provide a lot for it to work with, which may actually work out surprisingly well at times too if you want a lot to happen in one go.
