Alignment conjecture for virtual crystals $V^{r,s}$

For $4\mathfrak{g}4$ of type $D_{n+1}^{(2)}$, $A_{2n}^{(2)}$, $A_{2n}^{(2)\dagger}$, or $C_n^{(1)}$, let $V^{r,s}$ be the virtual crystal embedded in an ambient type $A_{2n-1}^{(1)}$ crystal. An aligned virtual crystal is one whose inherited intrinsic energy agrees with the prescribed virtual grading under the alignment conditions defined in the paper. Alignment conjecture. $V^{r,s}$ is aligned. Alignment is needed for the virtual crystal to inherit a compatible intrinsic energy and supports the subsequent identification with the desired affine crystal; the source leaves this property conjectural.
