All BYG wood variants are missing the whispering door recipe. They do have the whispering trapdoor recipes.

Relevant mods installed:

• mcwbyg-1.19.20-1.2
• addonslib-1.19.2-1.3
• mcw-doors-1.1.2-mc1.19.2forge
• mcw-trapdoors-1.1.4-mc1.19.2forge

Looking at the recipes within github, there is no aspen whispering door in 1.19.2 or 1.20.1, but there is in 1.21.1 and onward. I solved my issue by adding in a KubeJS script for those recipes but figured you may want to be aware of it.

Thanks for create this issue, will be fix in new version after Windows update.
