I have been enhancing some of the code that processes zip files and it looks like I missed that spot. I'll see if similar changes help here.

[LittleWhiteFoxy]

From the modpack creator : "the serverpack I provided already has forge installed"
Would this create an issue ?

[itzg]

Auto CurseForge uses the client modpack with metadata not the server pack which lacks metadata and breaks automation by bundling the modloader.

[itzg]

If you're communicating with the modpack author it's because they used an unusual zip compression scheme that breaks Java's standard zip support.

[LittleWhiteFoxy]

My curseforge link is wrong then, since i used the server file.
I'll try again with the client modpack then

[itzg]

Yes, I just noticed that also.

It appears to runs smoothly now thanks :p
Might need this info to be more explicit in the documentation, I read the doc multiples times but haven't found that information.
