Disconnecting after changing job.

I am having a weird problem with v117 where I disconnect to the login screen after changing my job. Is there a reason why this is occurring? What's weird is that when I make a adventurer, I am able to change my job into other advent classes but I can't change it into Legend or Res jobs.
This happens Vice versa with the other classes.
I only dc if I do ANYTHING. If I get a Item, If I kill something, I will disconnect seconds later.
