How to keep non-solder technic modpacks from overwriting files

[Fredigar]

Hey guys, I'm trying to modify the version.json of my modpack, but everytime I launch the modpack, it is overwritten from the cloud. Is there any way I can keep Technic from overwritting this?

In my case, I have limited internet, so I would like to test the changes instead of uploading to the cloud, and then downloading again.

Thanks for the help! I really appreciate it.

It's not updating from the cloud. It is being extracted from the modpack.jar file. Any changes to version.json must be made to the version of the file inside the modpack.jar archive.
