hi, i've an problem when i would like to launch world. 
 Deluxe Furniture: Modern by blockception was bought to play on it. When launching the server on this world, the game loads the files and tells me that the import was successful but remains for a moment on the percentage and gives me a message such as an error has occurred so the world is not created. I bought this pack to play on it and a realm subscription so that my friends can play with me or without me but it is impossible for me to play on the world. Could you help me because I don't want to have to pay for nothing
