What on earth happened to the beta server?

 Wrong place, theres nothing wrong with it, its still there

Ok so, once it comes to the custom tardis's back from (Hire SWD) what happens to them?, will the creators have a chance to update their interiors?

If you can find them go ahead and ask if they get readded

Does dmu 1.16 have the same textures as the 1.12 textures?

 Yes, 1.12 already has the 1.16 styled textures. 

Firstly, I recently installed your mod and love it!

Also, have you considered a feature where the player can collect resources/kill daleks to build their own dalek shell? You could even implement upgrade modules, for example, getting a flight module from  a time war dalek will allow the players dalek casing to fly!

RollorKart, That's a pretty decent Idea! 

If you want you can consider putting that idea in the SWD Community Discord Suggestion Channel.
