R markdown: figure-html folder not showing up?

Hi I'm experiencing a weird issue whereby figures generated "figure-html" during the knitr is missing. It use to be that when I render an rmd file this folder is automatically generated with all my figures. However, it no longer does this.

Here is an generic example:

---
title: "test"
date: "`r format(Sys.time(), '%d %B, %Y')`"
output:
  html_document:
    df_print: paged
  number_sections: yes
editor_options:
  chunk_output_type: console
fig_caption: yes
pdf_document:
  fig_caption: yes
classoption: a3paper
toc: yes
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## R Markdown


```{r cars}
library(ggplot2)
ggplot(diamonds, aes(x=carat, y=price, color=cut)) + geom_point() + geom_smooth()
```
