Lol, yesturday I found some ice pack, after 5 min I got stuck in the frontier border, died of glitching in the invisible wall.
Yes, I had the unfortunate mis-hap of hitting the invisible wall. Unfortunately it was in the side of a hill, and it kept trying to warp me inside of dirt to suffocate me. Spammed my chat so was harder to see. Got down to 2 hearts, somehow managed to slightly move to get out of it, and really carefully made my way back. I got really lucky as I thought I was a goner. Wish there was a warning 10 blocks away from the wall, and if you hit the wall it would warp you back to your 'warning' spot... Be extra cautious around the invisi-walls.
