I was at Blue Dragons under Tavelry, casting chaos bolts and alching gold amulets simultaneously; as I stepped out of the safe spot, my character froze. The dragon could still attack me, and other players were still killing blue dragons and moving around, so I don’t believe this was a typical disconnect; I wasn’t able to eat any food, I wasn’t able to teleport, I wasn’t able to move and, of course, the dragon killed me. When I spawned in Lumbridge, I was still wearing all my robes, but the other functions of death appeared to remain intact (all items were lost besides three). When I went to equip a weapon, my character changed state and lost the robes that were previously being worn.
This occurred on World 16 on April 8th, around 19:01. It may be possible to dig around in the server logs to see if anything seems out of the ordinary. Luckily, I only lost ~80k in value. But, I decided to report the bug here as I could imagine this being incredibly annoying if somebody lost their cash stack, etc. I will return to Blue Dragons and repost if anything similar happens again.
