[14:04:29] [Worker-Main-1/WARN]: Texture create_questing:item/blueprint with size 18x18 limits mip level from 3 to 1
[14:04:29] [Worker-Main-1/WARN]: minecraft:textures/atlas/blocks.png: dropping miplevel from 4 to 1, because of minimum power of two: 2

The following texture in create questing is breaking the mip levels in the atlas. All textures must be a multiple of 16x16 to preserve mipmapping. You'll need to update these textures to resolve this issue. In your case, this texture should be updated to 32x32.
