Hello, I've recently played Dalek Mod Universe, and I liked it a lot. But now my tardis might still be in flight, whenever I try to enter it shows the message "Cannot Enter Tardis During Materialization" even though it is not materializing. My friend tp'd be in the interior (I saved the cords) and I could not interact with the lever. It may still be in flight but not really, I don't know, Please Help! 

Edit: I also have a lot of important stuff in there! -TheOrdinaryGamer

A few things I would like to know,

The interior coords. I had a case like this once and I couldn't interact with anything. Restarting Minecraft didn't help so I had to ask some staff for a new exterior . You might need to do the same thing and do the /tardis-interior-pos x y z command with your old interior's coordinates subbed in.

Does it say 'This is not your Tardis'?  If so somehow your ownership perms were changed.
