MC-125807 is about trees, my report is about an anomaly of kelp. They are both chunk errors (I assume) but this isn't a dupe.
Responding to "https://bugs.mojang.com/browse/MC-126201?focusedCommentId=437340&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-437340"
It's the same issue essentially; it's an entire chunk out of some random block. (Although that report currently covers a different bug as well)
