MC: 1.15.2
Forge: 31.2.36
Mod: 1.12.9

issues:

1. Containment chalice is not pulling from a nearby lightwell as the book suggests, it used to behave this way in 1.12
2. Containment chalice has a bigger buffer (says 24 buckets in the book) but its definitely bigger

comments:
there is a possibility that the entry isnt updated in the book yet, if that is the case and these above issues are intentional please close the ticket
