I found some some glitchs.
First is when a shooting star LANDS and we're mining all of a sudden a golem appears and he can walk over the shooting star(just as you did with wall thingy @ GWD)
^ this happens for every single npc. it can walk over the star no matter what.
Second, Weed4u2 invested that a autoer called '0o0' was botting(ghost mouse) mining earlier this day. And when i was there i saw him but he couldn't mine, because the golem appeared behind him(wall) it was stuck there(inside the wall) and couldn't attack him.
Third this was reported by my cousin. When you ever have the OPEN GL client on. and u wanna go to barrows, for some reson the portal is not there at canifis. and u gotta restart the client for it.
Fourth, As you all know ALL untradeable items drops when you die. This comes to a equation where mining ring drops when you die, and doesnt appear afterwards... Its pain in the ass to get 1.5k stardust all over again.
Cheers.
