So I accidentally destroyed my TARDIS interior so I started to test out the different doors to see if I can find the right one, I noticed however that some doors SOTO works but some doesn't, sometimes when I open the doors theirs nothing but and open sky and a bottomless pit. I have optifine but with fast render off 

I have the same problem. Also when my TARDIS has flight panel interior doors that I see through boti are flipped over. Does anyone know how to fix these both problems?
