Some spiget resources reapond with octet-stream content type

[itzg]

But now I'm now getting this error, is it related or should I create a different issue?

[init] Getting plugins via Spiget [init] Downloading resource 2124 ... [mc-image-helper] 02:49:10.485 ERROR : 'get' command failed: Unexpected content type 'application/octet-stream', expected any of [application/zip, application/java-archive] [init] ERROR: failed to download resource '2124' from https://api.spiget.org/v2/resources/2124/download [init] Visit https://github.com/SkinsRestorer/SkinsRestorerX/releases/download/14.1.13/SkinsRestorer.jar to pre-download the resource [init] instead of using SPIGET_RESOURCES
