I think I missed it it the patch notes, but it feels like since the last patch, the npc guards now have chains, and they're pretty glitchy. When it's particularly laggy, I end up hearing the chain, then seeing the animation, then a couple of seconds later get slowly dragged towards them.
I had it happen tonight too, that an npc on top of an enemy keep did this laggy chain thing to me whilst I was sieging and I ended up on top of the wall . I promptly got killed by yellows, but nevertheless, if it was able to be consistently replicated, then it would allow people to jump into keeps without sieging, which i'm sure you can imagine would be pretty unfair.
Has anyone else experienced this?
