Publishing/unpublishing makes stache mess up sometimes

[riasvdv]

Expected behaviour

Stache doesn't mess up

Actual behaviour

Stache messes up and throws an error comparable to this:

Cannot add [collections/social_map/_francais-107.html] to Stache repository [entries]. File at [collections/social_map/francais-107.html] already exists in repository [entries/social_map] with an ID of [5d9e128a-6957-4e64-81fd-d4dce5e1975b].

Steps to reproduce

Can't reproduce it consistently but it happens once every few days and then the whole control panel locks up and the client complains. Maybe just a way to not have it crash completely would solve a lot already.

Add ensure_unique_ids: false to system.yaml to prevent those checks.
You might run into other errors, though.
