It looks like it was for the Bass Pro Shops patch that didn't work properly at launch. https://twitter.com/DovetailFishing/status/1328669331656413184
Hi everyone, yesterday's patch was for the issues that came around after the Bass Pro Shops Equipment Pack came out. I have updated this thread here with the 3 fixes we included in the patch - Patch Notes As for the size of the download, this varies between platforms due to the patching process. Some players on Xbox may find it is a full download again.
