Changes made to a packages code keeps reverting

I've tried to fix an issue with a package I've downloaded, and any time I restart unity these changes seem to be reverted. The package hasn't been updated or anything, so I'm unsure why it's detecting changes I've made and rolling them back.

Anyone know how to disable this?

 

If the package is from the package manager, it's stored in a central location for all projects to use and from what I've experienced, changes there don't save. I've always had to copy that into the projects individual packages folder and then make the changes to the copy.

 

Hrm, this sounds like it's going to blow up my project.

edit: I stand corrected. It was literally that easy. Thanks.

 

How does that work? did you remove the original package? I just get 'class already exists' type messages when I try this.

 

I'll use textmeshpro as an example. The version I have in the main package folder is
com.unity.textmeshpro@2.0.1

If I want to make changes to those files, I would copy this folder into the project package folder and edit it to be
com.unity.textmeshpro

Then start the project up and textmeshpro now points to the local project package and not the central one. If you are getting duplicate errors, you need to see if you have duplicates inside your assets folder of something. You should not get conflicts from the local and central packages.
