So, I was playing OITC, and something happened to me, something very annoying. This video is a reconstruction. When the real moment happened I didn't record and got killed. Can this be fixed? I know it's a small thing, but it was a pretty silly death.
I don't think it is much a problem. Just don't get near the beacon when shooting a bow. It's not a bug, its how minecraft beacons are made.
I know it's not a bug, but it's just annoying when you get 'killed' by a dead object, and it can be easily changed.
It can be a big problem for close calls though. There is a way of fixing it, and that's world guarding the beacons, it will stop people from using them, and it'll just come up with the permission message.
Kris is right. You can accidently click the beacon and get killed. This got reported by @iPr0xyy before, but never got fixed. It's the same as the anvil bug.
