Data driven blocks throwing content log errors on realms

One of our products throws content log errors on startup in Realms. This does not happen when not on realms. Presumably this affects all maps using data driven blocks

Verification builds:

Unknown. A 1.16 build used by Certification on 7/13.

Summary:

Description: Content log messages appear upon creating and loading to the 'Advanced Crafting' world on realm. – Specifically about data driven blocks.

Impact:

Small, as long as CM passes it through since we can't fix this realms specific bug on our own. Then it's just some content log spam for the subset of users trying to play on Realms.

Repro Steps:

1. Run a map with 1.16 data driven blocks on Realms (presumably, it's any map that will cause this, as we didn't do anything special with ours)
2. Observe content log

Observed Results:

See attachment- Content log errors appear. (and possibly, the data driven blocks aren't working either? we don't have the ability to repro this ourselves currently, this came from Cert)

Expected Results:

No content log errors, and data driven blocks work.

Screenshots/Videos attached: Yes

Regression Builds:

Possibly never.

Notes:

(Anything else you would like to say goes here.)
