Changes
+ Enabled mover caching system - This is experimental, the performance improvements are immense by enabling this system. However in the past it had issues so I will disable it if needed.
+ Train stations now sort their inventory when their inventory has an item at their max total limit. Most items have a max limit of 256 in the station or 4 stacks.
+ Train stations now rebuild their connected stations every 30 seconds. (This heavily improves performance)
+ Train stations rebuild their connected stations immediately when someone is viewing their inventory.

Fixes
+ Fixed an issue with trains where renaming the train and removing it would cause a spam error.
+ Fixed an issue where items with 1 stack amount would all move at once if possible.
+ Fixed an issue where movers in chests could move more then 2 items at a time of different stacks. This actually heavily improves performance.
+ Fixed the autoplanter in 1.21 erroring on start up due to new saplings.
+ Major performance changes for electric furnaces, over drivers and power grids. About 5x more performant now.
+ Performance went from 11 milliseconds per tick to 0.7 milliseconds per tick. To give an idea you need 20 mspt to experience tps loss or lag in regular terms. This was done on my personal pc using a test server provided by fluffy with over 2.3k devices on it. With these improvements we could see about 60k devices on a server now before losing tps.
+ Technical change to item serialization, items with damage on them that are not normally damageable no longer persist. This fixes an inconsistency between spigot and paper. This fixes 1.21 crafters from not working
