I love this mod and it is essential for every playthrough of HL2! HOWEVER it still messes with my new games whenever I load up the episodes even after the fix and unsubscribing from the mod on the workshop. If you don't want to delete the VPK file manually or whatever, just load this in the console.

1. Open console
2. For a new Episode 1 playthrough, copy and paste this: "map ep1_citadel_00"
2. For a new Episode 2 playthrough, copy and paste this: "map ep2_outland_01"

Now you don't have to uninstall this beautiful mod to play the episodes. Thanks, and have fun.
