Go to your folder on Xenobot and u will see Data, open this folden and find the last version of it... (it.0023.15.11.28.1249)
then open it with Text editor and find corpses, add this: <item id="CorpsesID" fish="1"/> and now will loot.
PD: Close all tibias and xenobot before add id.
If you have any problem feel free to ask.
