What was the user doing before this: making tardis

Location of bug [E.g. Servers]: DMU

Status: Unsolved

Description: So when I finished crafting my tardis (first one of update 56) and when I tried to place it it said "you can one have one tardis" when I didn't have a tardis. 

What it affects in-game: not able to have a tardis

Image: don't have any

Any other information: I had a tardis in the last reset

Try going to the world folder and remove the "Tardis_data" folder or something like that once you've done it, go back into the world and try placing the tardis

 He's on DMU, not his own world.
