I play on SP and got a 160 Wyvern egg. I built a trap (4 B.Gate) for milk and went there to set the trap, stopped to recharge stam and this little fella just stole my gates. I couldn't chasing him, he went to the Red Woods and there's the cat on the trees. Really sad.
If you’re tired of getting robbed of gear try this. Put spoiled meat as your last item in your hotbar and carry a few stacks of meat. They’ll typically take your spoiled meat since it’s the last item and you’ll replace it over and over.
