So I have lost my tardis in the nether and have absolutely no idea where it is so a friend of mine made me a new one which was nice of him but when trying to place it down it says I cannot have more than one tardis. Is there any way to disown my previous tardis in order to place my new one, thanks in advance.

You need to give away your tardis,by using the command /tardis-ownership nameoffutureownerhere ,but you have to do it with someone that is aware about you giving it. If we find out players give away tardises without asking for permission first,the punishment is a ban.

Thank you very much I really appreciate it. :)

 I just found someone who wanted it and when putting in the command it said 'This is not your TARDIS!' Does this mean I cannot do it?
