There's an old issue about this #303, but its marked as “information needed” and theres no activity since.

This issue will just act as a reminder as the devs already know the details.

It shouldn’t be a big problem if there wasn't an item display feature, but it's disturbing when you open a filled fridge only find out it looks empty.

Please work on this asap, thanks in advance.

Ok then, just thought it was long lost and forgotten.
This is my new favorite survival mod, I would love to help clear things out and get rid of this bug.
I will do some experiment on it and report the results under the other ticket.
It's on a superflat world where I run into this problem btw.

Thank you for fast reply as well.

Its best to just comment on the other issue, now you are making another "ticket" for an issue that is already open.
Just comment there and post your findings, how did it happen? Can you take pictures or are they the same as already posted, does this issue only occur in the ocean biome like the other user already said?
What version of CfB do you have?
What minecraft/forge version do you have?

If we can isolate this issue to a specific version, it would be already a big help.
