"Displaced" portal - have to enter portal twice to go through

If you enter a portal in the nether that is "displaced" by a faction claim in the overworld, on the first attempt, the portal in the overworld DOES generate, but you get the message "The other end of this portal could not be generated". You have to re-enter the portal on the nether side to go through. The check that prevents you from going through may be taking place before the portal generates in the overworld (hence you have to enter the portal twice)
