Additions
+ 1.21.9 is now supported.
+ Copper chests are now seen by movers.

Fixes
+ Model data fixed so it should now apply to items when setting their model data.
+ Hoppers can no longer move items into movers. (This also fixes a minor issue giving the illusion of deleting items)
+ Optimized pipelines, they were producing alot of overhead, on my own server it brought it from 2.0mspt to 0.03mpst.
