hi! i have a question:

Why when i put the dalek mod in my server, i can't spawn when i get in the tardis!

any idea?

The interior may not have generated yet, or conflicts with another mod. Do you have other mods that use dimension-generating? It may cause conflicts with the Dalek Mod. 

I see you're new here. Welcome to the Forums! If you wanted to ask that one question try posting here, it's better than making a whole thread just for your one question titled 'server'.  Link: https://swdteam.co.uk/forum?p=thread&tid=9&page=8#t_post_id_2435 

haha :p yes i'm new! thx for your answer :) just.. i've done some tests like get in the tardis in singleplayer, it worked fine, i've copy the world in my server and it doesn't spawn again! :(

 Try loading up a new world on your server and see if you can place a Tardis in and go in it. Also maybe try some different variants E.g. Vanilla Tardis, 1963 Tardis.
