Additions
+ New Config Option, Use Mover Caching, by default this is set to false. Enabling this allows you to use an experimental feature that has not been fully tested yet. It can improve mover performance by insane margins though.

Changes
+ Web poison has been reduced from 10 second to 5 seconds and its strength was reduced by 1.
+ Spider web debuff range reduced to 32.
+ Super Chunks will now slowly dissipate evolution as well. Though this will take a very long time compared to pollution dissipation. It will go down about 3.5% evolution per day.
+ Nest Spawn Timer changed from 300s to 900s. This means super chunks by default will only attempt to spawn new nests every 15 minutes rather then every 5. (This didn't actually get updated in 0.78 for some reason)
+ Biter nests now get destroyed in a way cooler way, over time with some sound effects.
+ When a nest is killed biters now lose half their health.
+ Defender biter respawn time at nests increased from 10s to 15s
+ Gold Nugget chance reduced from 10% to 5%
+ Iron Nugget chance increased from 15% to 20%

Fixes
+ Broken movers now properly remove when being placed and broken rapidly.
+ Slightly changed how super chunks tick landmines, generate dissipation & dissipate pollution, this should improve super chunk performance.
+ Optimized motorized mover carpet checking. It will now only force check once, after that it relies on players being nearby in order to attempt staging a rebuild for its belt.
+ Belt movement direction is now cached on success this should improve belt moving performance.
+ The Crafter will now display current ingredients correctly.
+ Nests will now remove all of their nest blocks. However already spawned nests will use the old removal method, which can still leave some things behind like cobwebs.
+ Fixed an issue causing chunks to stay loaded in cases when they shouldn't have due to devices.
+ Fixed an issue in 1.21.2/3 with items bouncing into the air.
