I have one friend that never leaves the lobby when a new game is started.
I will take any suggestions on how to resolve this.

*it is worth mentioning that I have about half a dozen other people and none of them have this issue, only the one person.
This person is in the correct version and has the resource pack enabled

Hey,

thanks for letting me know. I thought this would not happen anymore.

Which version of the map are you using?
And how did that player leave the resource pack check room? Did he leave the usual way by clicking the chat message, or were they somehow teleported in a different way?

would have to double check, but pretty sure we are on 5.0 pre1
And now that you mention it, yes, he was teleported from the check room- had totally forgot about that

They were teleported, as in teleported manually?

Yeah, that's not supported, everyone needs to go through the rp check properly, otherwise the player is not setup properly. I should probably prevent manual teleporting, to prevent issues like this.

I would recommend updating to the latest version (currently on 5.0 Release Candidate 3).

To fix the issue with the player, since they never did the rp check properly, they should still see the chat message when they join. Can you tell them to go through the instructions from the message? This should fix the issue.

Thank you for the quick reply, appreciate you!

*We initially teleported him in to the lobby because they were not able to do anything in the check room- clicking on signs had no effect

This was fixed in 5.0.1 in 24b88fd
