Custom World Generation Features Stop Working After Exiting And Joining Back Into A World

Custom features for addons such as features, feature rules, structures, and many other things that affect world generation stop working after exiting and re entering a world with an addon that has these features. If you want to recreate please use an addon with features, feature rules, or structures and then once one of your structures have generated please exit your world and re join it. Once you re join no more custom structures will spawn.
