I can't download the modpack anymore from the Twith client . After downloading a big part of the mods, it stops and cancels the installation. The error is : "cannot find child addon : 262691. The issue has been addresed several times by other players in the problem section of the modpack page here. But no answer so far. And I doubt it will be fixed anytime since it's an old pack now.
Is there any other way to download the last version of this pack other that the Twitch client?
