Selectively11/STFixer v0.7.1

on GitHub

DLL downloads now use mirror — primary source (official ST updater) still uses HTTP. In order to prevent ISP/antivirus tampering that was causing hash mismatches for some users, I switched from the primary to the secondary. This is a cosmetic change, the app already hash compared the two sources.

Better payload diagnostics — "unknown payload version" is now split into "payload corrupt" (can't decrypt) vs "unsupported payload version" (unrecognized signatures), with actionable guidance

Option 4 cleans up bad payloads — after repairing DLLs, if the payload cache is corrupt or unrecognized it gets deleted automatically so Steam can download a fresh one on restart
