I was currently working on a custom theme for a client and upgraded Magento from 2.3.2 to 2.3.3
I went to save a category image initially and it worked like normal. Then I went to resave the image and it disappeared. At first, I thought this might have something to do with my code.
I decided to install a base Magento 2.3.3 install with no modifications and it's doing the same thing.
I noticed that when you resave the category the image gets a '_1' without importing a new one. I looked in pub/media/catalog/category and that image is not there.
Any word on what this bug could be?
