And put it back when you need it. There are couple of mods that can help you with this. I can help if you don’t know how.
But this will not solve your problem. I think the easiest way to solve your problem will be to change your “friends”
Or to force everyone to play with server characters mod - this mod will save characters on the server and players won’t be able to log in to other worlds.

well that mod shouldnt be a mod but an official part of the games functions.

Yeah, and a couple more. I hope they will add mods to steam workshop once the game is finished.

I really feel sorry for you. I never had any bad experiences on my servers. We add one player at the time and we have some kind of an interview with new members before they join. If they say their mic is broken or cannot talk at the moment, I simply tell them to let me know when they fix it. They most likely don't have good intentions if they are not willing to talk. Maybe they are hiding their childish voice :)
We had 2 of them in our discord server and as soon as they found out they will not be allowed to play without talking to us first, they showed their real face.

As I said, use servercharacters mod. There is no other solution against this kind of players. They can still make a mess, but they won't be able to do something that will mess up the whole world progression.
