The Limitation for salvage Computer and salvage modules are wrong way around.
This liits the amount of Computers:
<Controller>
<ID>4</ID>
<GroupMax>200</GroupMax>
</Controller>
And this Limits the amount of modules:
<!-- Salvage Computer -->
<Controller>
<ID>4</ID>
<ComputerMax>1</ComputerMax>
</Controller>
