I get the feeling the original poster was inquiring to other, existing 4.85 servers - wether or not those will be forced to update to 4.86. I don't think this is the case, although I doubt you could log onto a 4.86 server with a 4.85 mod client, or vice-versa.
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
