No changes were made before this problem started. The project stayed in its current environment and no upgrade was made. This is running on sitefinity 5.0. The page the images live on was not moved either.
I added a custom field to images that allowed long text input. Images are embedded using the WYSIWYG tool into this field. Somewhere down the line these images stop working. The images are not moved or changed in anyway. I can edit the image and the image will re-appear. I can resize the image, crop the image and save and the image will reappear. However they will continue to be broken unless I re-link the image or edit the image in some way.
I attached the example input for what I am doing. After an unknown amount of time (seems random) the images will break (shown in the original screenshots).
