XPath Patch Failing

[SihvMan]

I need some help.

I am attempting to use the new A17 xpath patching method to replace the tusk that drops when butchering elephants. However, each time I try it, it kicks out a red error message with a hard to understand error log.

Here's the code I'm using to patch;

          <bodyPartGroup>HeadAttackTool</bodyPartGroup>
  <thing>SkeletonElephant_minified</thing>
        </butcherBodyPart>
  </value>
  </Operation>

</Patch>

I'm pretty sure the butcherBodyPart is in the lifestages, so you're missing a few steps in your xpath.

Don't have code on hand to check at the moment, so can't point out the specific mistake/give an example.

That was it. I needed it to be

<Patch>

  <Operation Class="PatchOperationReplace">

instead.
