Acyclicity conjecture for the Quilt operad

Let $\operatorname{\textit{Quilt}}$ be the operad of quilts, and let $H_k(\operatorname{Quilt})$ denote its homology in degree $k$. Acyclicity conjecture for the Quilt operad. $\operatorname{\textit{Quilt}}$ is acyclic in the sense that

$$H_k(\operatorname{\textit{Quilt}})=0$$

for every $k>0$. This conjecture concerns the homological structure of the operad governing operations on the Hochschild bicomplex of a diagram of algebras. The supplied text gives no evidence that the claim has been resolved.
