Spoilers not working for some reason

And why are you posting this here? we cant just  press a button to make your problems go away. Your on a snapshot, Of course it will be buggy as hell!

 I agree

Well 1.13 is not really our problem since The Dalek mod is not on 1.13. If you got problems with playing the 1.13 snapshot I suggest you go to the minecraft forums.
