2 Sumo buggs in 1

(Both buggs in one screenshot)

First bugg: Sword Breaks , it bight be lvl x but it still breaks maybe higher durbility?

Second bugg: It said i fell off but im still on top of the map:

 

First one I've seen before, if you hit people a lot, your sword will break but next round you'll get a new one. The idea is you don't usually hit that many times before getting hit off xD
Second one not too sure of, perhaps it's because of the lag you said you have had recently?

 

Actually, the second one happens to anyone. It happened to me many times, what happens is you go very close to the edge or you lag back in the map then your name goes white and you can't hit people nor can they hit you. It makes you look like a anti-knockback hacker which is why when it happens to me I jump off. It's the weirdest bug in my opinion. I suggest that they make the thing that makes it say you fell off lower like it only says it when you touch the ground or something.
