when i was playing single player, ( with disqualification) i carried this guy up and jumped when i landed on my feet it say disqualification why?

and if u want see the replay here

Its an ankle glitch. Its happened to me in 2.2

You hit the ground so hard your ankles touched it.

It's neither new nor glitch, it's known as 'ankle break' from very early versions, meaning you land too harshly, your foot clips through the ground and your ankle's hitbox goes near enough, DQing you, perfectly normal thing to happen.

Its annoying, but something you get used too.
you learn to perform more subtle landings, leading into easier finishers...

There is a server setting that takes away DQ on ankles and wrists. It is enabled on judo servers.
