There's a slight bug with warped and crimson planks. When you try to craft wooden tools from them, it won't craft them. The recipe isn't allowed. This is the only bug i have encountered with 1.16 beta so far. The main problem is that you can't get stone, which makes surviving in the nether hard. Especially if you wanted to do the nether survival.
Thank you for your report!
