Wow, I have no clue what is going on. But I am having the same issue when I download the file from the server.
I zipped the files again and re-uploaded it. Same issue.
Thank you for the head’s up. I will keep trying to sort this out.
But in the meanwhile, if you’re anxious to upgrade, I would say to go for it.
The files are 207 MB (217,666,381 bytes) before zipping, and exactly 207 MB (217,666,381 bytes) after zipping, uploading, downloading and extracting. So I’m confident every byte is accounted for despite the error.
