Official Steam icon assets on SteamGridDB point to cdn.cloudflare.steamstatic.com which is replaced by cdn.steamstatic.com when you follow the link on your web browser, SGDBoop however, doesn't do it, and writes
<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently</h1></center>
<hr><center>cloudflare</center>
</body>
</html>
to the output file.
Reproduction steps:
- Open game page on SteamGridDB,
- Select "View Original Steam Assets",
- Select "Boop 'em all",
- Select your Non-Steam game,
- Navigate to
C:\Program Files (x86)\Steam\userdata\[steam user id]\config\grid,
- The file for the game's icon is corrupted, and has "301 Moved Permanently" written in it.
