Changes

• disable-collisions is now false by default. With collisions off, entity cramming no longer kills silverfish, so if a farm keeps running while nobody kills them, they pile up without any limit and can bring the TPS down a lot. With collisions on, cramming keeps at most 24 in the same spot.

You can still set disable-collisions: true for a bigger saving (about 35% to 57% instead of 20% to 35%) if silverfish are always killed soon after they arrive. See the README for details.

Default config

enabled: true
disable-collisions: false
prevent-drowning: true
push-off-campfires: true
worlds: []

Requirements

• Paper 26.2
• Java 25

Updating

Replace the jar and restart the server. Your config file is kept as it is, so if it has disable-collisions: true, change it to false yourself and run /fsf reload.
