Verification builds:

1.14.0.2

Summary:

Some log blocks (id "log") in chunks that have an old format are converted to Wood blocks (six-sided bark, id 'wood') since 1.14.0.2. Not all of them get converted.

Impact:

This affects builds to some extent, and even breaks logic that relies on those affected blocks being logs. One example is Dreamland (live), in which there is a command that testforblocks a log to check if the chunk is loaded. That block happens to be affected by this bug and now the map act as if those chunks are never loaded.

Repro Steps:

1. Create and join the provided world (sent to Greg via Slack).
2. Pick-block the oak logs that make up the ship's mast.

Observed Results:

You will get Oak Wood from the majority of blocks.

Expected Results:

You get Oak Log from all the oak log-looking blocks.
