Ionic serve wipes

Hello all.

I installed ionic sass, but every time I run ionic serve command, it wipes the and the files.

I have to replace them each and every I run ionic serve

Any help is always appreciated

when you run ionic serve, your sass files will be generated to css. You should be making style changes in your sass files, and not your css files. On build, sass will compile to css which is then referenced in your index.
