Custom Animation Node Will Not Use Input Pose

I’ve been working on a custom AnimNode, and it works for the most part, except it will not use the input pose. See attached:

I know it’s evaluating because the arm is a different size. However, it will not use the input pose. The node is based off the AnimNode_ModifyBone which just applies a transformation to a particular bone, except I can’t see anything that would be causing this issue. I’ve even recreated the ModifyBone node and tried ripping it up to see if I could recreate the issue, but to no avail.

Code for the Node:

Overall I’d appreciate any insight as to why this would happen, as I cannot recreate the issue in another node. I haven’t logged any errors from it either.
