Crushing Tub only processes every other jump

[vishtheshnu]

Currently using Rusticated 3.0.1 on Fabric 0.15.7.

When I jump or otherwise fall on a Crushing Tub, only every other fall actually counts for crushing its contents. Even having multiple tubs in a row and jumping between them, only every second tub actually takes input.

This happens when jumping on the same spot on the tub, and using different inputs (olives, grapes).
