Help with Patching

[cory3573]

I am attempting to Patch the Orbital weapons and the Low Shield Pack to be refuellable using the bits of another mod (Buyable Quest Rewards) I have installed.

I've tried various different patching methods but I can't seem to target the "CompProperties_Reloadable" li or even the comps of each item.
The section I'm modifying is

Code Select Expand

    <comps>
      <li Class="CompProperties_Reloadable">
        <maxCharges>1</maxCharges>
        <destroyOnEmpty>true</destroyOnEmpty>
        <hotKey>Misc4</hotKey>
        <chargeNoun>charge</chargeNoun>
        <displayGizmoWhileUndrafted>false</displayGizmoWhileUndrafted>
      </li>
    </comps>
I want to remove the destroyOnEmpty (I was trying to remove the entire comps node at this point) and add in refuel parameters with these(might need to be li[0]?)

Code Select Expand

<Operation Class="PatchOperationRemove"> <!-- Recharging Tornado Generator -->
<xpath>*/ThingDef[defname="OrbitalTargeterBombardment"]/comps</xpath>
</Operation>
<Operation Class="PatchOperationAdd"> <!-- Recharging Tornado Generator -->
<xpath>*/ThingDef[defname="TornadoGenerator"]/comps/li[1]</xpath>
<value>
<ammoDef>Chemfuel</ammoDef>
<ammoCountPerCharge>50</ammoCountPerCharge>
<baseReloadTicks>60</baseReloadTicks>
<soundReload>Standard_Reload</soundReload>
</value>
</Operation>
I also tried replacing the entire list and comps nodes but I get an error every time

Not sure what I'm doing wrong but my next plan is making a separate mod folder and trying to mod the files directly but that's just mod conflict central.

I figured it out myself after a few hours, moved all of my various changes into a new mod of my own and went through rimworlds complaints. Ended up figuring out the problem as long as I load my newly made mod last. Seems it was an issue with context, make sure you spell and position everything PERFECTLY
Ended with this code for the comps replacement
