    Just upgraded to 2017.3. Cloth is ESSENTIAL in our game and this is requires a patch ASAP.

    I created a script that finds all the Meshkolliders and removes them. But this is certainly not the solution ...

    I just found workaround. Disable Cloth gizmos and when applying prefab make sure Cloth component is not visible in inspector. It works for us.

    Looks like it creates temp meshcollider for painting/editing tools and when hitting apply it saves it into prefab file.

    Actually after step 4, you can see two MeshColliders are added to the prefab instance already.

    Voted. Also, though anecdotal, It's been a bug since 2017.3.0b1 as far as I know.
