The latest launcher update (1.6.51) has brought along a major bug.
When a new .json file gets created, a new "downloads" argument is added. That arranges it so that each and every time Minecraft is launched, all files are downloaded again.
Shouldn't that only happen if files are missing, or if a new Minecraft version is getting loaded?
Whilst this "downloads" argument is still in the .json file, it's impossible to install mods as well, because the Minecraft version gets reinstalled each time Minecraft is launched.
There is a screenshot of a comparison between an old .json file, and a new one, with the "downloads" argument (marked green).
Or is this whole matter deliberated?
If not, please fix it 😃
Kind regards
HuanZon

Is this still a concern in the current Minecraft Launcher version 2.0.805 / 2.0.806? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.
Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. It will be reopened it as soon as the requested information has been delivered.
yes because, I am unable to install forge on 1.4.2 when it use to work. I had to delete the assets from the json and it's still not working
For me, it works if I replace the appropriate "sha1" value in the json with the sha1 of the modified jar.
I am not sure why this is marked as "Resolved" when in reality it isn't.
You still can't mod versions older than 1.6, even if you make a separate version, and so far for me, any tampering with the .json file confuses the launcher so hard that it refuses to even launch the game.
Reopened. The ticket was stuck in "Awaiting Response" since the reporter of this ticket has not answered.
Thank you for your report!
Closing as Cannot Reproduce.
