I’ll join the list. Made my Mysterious Vine days before patch and had the Cultivated Seed in my charracters inventory. After the patch the Cultivated Seed was turned into a Pet Seed, I didn’t think tto much about it and made it a Pet Seedling.
I Have also completed the other steps and this patchs story, and now find myself missing the Cultivated Seed, hope i don’t have to make the Mysterious Vine all over again.
