I was playing 1.7.10 on update 43 and the tardises don't work properly they mostly have the same interior and wont travel to plannets

Its true the most interiors in u43 got the same interiors because in u43 there werent many interiors yet thats why they almost got all the same capaldi interior.

In the U43 update for 1.7, the 1.7 interiors and planets were removed. It is now more like 1.8. If you watched the Update review, Matt explains this

Ok thanks
