Sorry if this isn't the right place to write this, but I'm getting the same issue.
I downloaded the files from https://sharemods.com/d41a3vriwxdd/frosty_8.scs.html and got 8BAE7ED44CDA4BF96FD5AAB1BF79C9D5A03566CD.
Both file downloaded in 12/28 08:19(UTC) and the one done now have same SHA-1 starting "8BA".
For "just in case", I payed $1 and downloaded from https://www.fatfreecartpro.com/i/107ha?card , but resulted same.
I don't know what's happening.
