We can not predict the failure of the PC, server or Internet. This is not to say that this is a frequent occurrence. But it forces to refuse use of iron vertical ladders. If at the time of failure, your character rises or descends the stairs, then at the entrance to the server, he does not hold onto the stairs and falls down. If a character is at a high altitude from the surface of the earth, he will fall and die.
Is it possible to change this development of events? It is necessary that the character would hold onto the ladder when returning to the server, or be on the ground near the ladder (did not fall).
