- Port player chunk loader patch
Makes the chunk system act as it did in 1.17, no additional tickets (and thus logic) to make a chunk ticking.
Adds simulation distance API, deprecates old no-tick method.
- More collision optimisations
Ancient patch from tuinity that never could be pushed to master.
- Fix Optimise ArraySetSorted#removeIf patch
- Execute chunk tasks fairly for worlds while waiting for next tick
- Port Replace ticket level propagator
