[MC-180327] Dark oak trees not bonemealing in a world updated from 20w16a to 20w17a

I have a survival world I've been updating with the snapshots for the nether update, went from 20w16a to 20w17a, and suddenly I can't grow any dark oak trees at all. At least not in old chunks which is where I've been testing. (I've also encountered other issues but you say to do one report for each.

Environment

Windows 10 64 Bit Pro, as far as I'm aware latest version of Java.

Are you using 4 saplings? You need to.

No clue if @s work but I'll try. Yes I am, and I've tried clear fields, night, day, rain, shine, set the game tick to like 2000 to see if they grow naturally, they just won't grow.
