I think I might've just busted someone on trying to use a new, powerful, unfair bug.
So, here's what happened:
I was farming in my village and I suddenly noticed 2 trespassing scents at my mine hole. I thought "huh, that's weird, there's a palisade down there. Someone must've bashed it. Lemme check scents"
So I went down the hole and bumped into 2 Dhelmers. My quickest reaction was immediately leaving the mine hole back to ground level, running out of my palisade above ground and locking gates.
They nearly got me, but luckily I locked myself out right on time.
Next thing I did was calling a friend who could help me get them. He went down the mine hole, but they ran away.
A while later I went down my mine hole to fix the broken palisade.

I went down in my mining node and found out they made this tunnel wider by mining. Odd I thought.

As I went further investigating scents I found a ram in the cave. A ram.
Now think this over.
They bashed a palisade.
There was no brickwall.
Yet... they build a ram?
My explenation: they found a bug where it is possible to bring a ram up a ladder to ram my brickwall.
