Additions

Added construct Stand Guard task in the lodestar. Will cause the construct to stand at attention at the given location and guard.
Added construct Guard task in the Bell of Bidding. This is equivalent to the current follow task.
Changed construct Follow task in the Bell of Bidding. This will cause the construct to passively follow you and not attack anything.
Construct Guard and Follow task in the Bell of Bidding can now be used on other players to have your construct guard them. This will not currently persist through world save/load or dimension change.
Added the ability for constructs to milk cows, and cow variants.
Added the magmoo, a very rare nether mob.
Construct take item now will put excess in a construct's backpack if available. Hands are prioritized.
Construct Patrol is now CO-LA-BO-RA-TION enabled
Construct Guard also makes use of CO-LA-BO-RA-TION. Only one construct can guard the same point at the same time (on the same lodestar).
Added a verbose prompt for capturing a wellspring without a faction clearly indicating that one is required
Added a verbose prompt for capturing a wellspring with the wrong lens, indicating which lens is required.
Added chinese translation; a big thank you to xiaoknya and TUsama
Added korean translation; a big thank you to mihile

Bug Fixes

Fixed a display bug in construct diagnostics; it now properly shows item quantities
Fixed an issue with construct patrol leash ranges
Improved ender leg teleportation AI
Fixed an issue with the Runic Anvil not accepting items from automation properly. Construct smiths celebrate!
Fixed an issue with the inventory management utilities causing incorrect detection of simulated item extraction
Fixed an issue with reagent consumption and result flags; which also fixed a duplication issue with crystallize
Fixed an issue where flowing water could replace transitory tile blocks; thereby deleting the original block
Made a change to projectiles to cause them to more reliably despawn clientside

Re-balanced construct backpack capacities
Ender affinity now affects the maximum slot size of a construct's backpack. It starts at 4 per slot if no ender affinity, otherwise 8xender affinity score.
Significantly increased the cooldown time on constructs plucking feathers from chickens. It'll work out to somewhere between 1-2 plucks per minecraft day, per chicken, on average. Milking cows carries the same rate.
