Scaffold buckets generate from the ground up, they are designed for gravity blocks but you can make them any type. These are an alternative to have vertical gravity buckets, scaffold buckets will be more lag friendly.
I also added per bucket block delay so that you can choose how fast each bucket will generate rather than just a general time for all buckets. Either generate a new buckets.yml or add this line to each of the buckets:
Please report any bugs, I hope you enjoy the update.Code (Text):
delay: 5 (delay in ticks, 20 ticks = 1 second)
