Roolo on "[Plugin: Advanced Custom Fields: Image Crop Add-on] Plugin not working since acf 5.3.6.1"

Acf pro 5.3.6.1 released yesterday and acf-image-crop is not working since. This is also reported in https://wordpress.org/support/topic/update-for-wp-441
but with the wrong reason. when I'm uploading an image I get the javascript error:
`Uncaught TypeError: acf.get_field_key is not a function
Please fix this.
