• Fixed a crash when opening certain guide pages. Thank you for your crash log, Ryk7039!
• Machines now update chunks a lot less often (this should improve performance)
• Updated code relating to how spectators can view machine GUIs
• Auto Workbench now correctly accepts FE when the BuildCraft config is set for machines to use FE
• RF/FE and MJ pipes now share the same rendering code, so any visual bugs that were exclusive to RF/FE pipes should be gone
• Editing a volume defined by a volume box or land markers now only updates that volume instead of every single one in the loaded dimension
• Items ejected from pipes into an inventory now top up partially-filled stacks before starting new ones, matching every other BuildCraft item output.
• Made the Oil generation code far more sensible; fixes multiple sources of freezes/server hangs on 1.21.1. Thank you for investigation, MapperTV!
• Updated the NeoForge minimums: 1.21.1 is now 21.1.151+, 1.21.10 is now 21.10.63+

• Items travelling through pipes no longer lose their enchantments, custom names, or damage when the chunk is saved and reloaded
• Builders and Fillers now reach their full building speed once their internal power buffer is half full, instead of permanently topping out at half speed even on a completely full buffer
• Fixed three of BuildCraft's four JEI plugins sharing one identifier, which could cause JEI to drop some of the mod's recipes
• Fixed FE/RF pipes not rendering their power sometimes (MJ was fixed the same way previous update)
• Fixed engines occasionally forgetting their recorded owner if they were placed and then never interacted with before their area unloaded
• Fixed the collapsible info/help ledgers flying up off the top of the screen when collapsed
• Fixed a "Network Protocol Error" disconnect when right-clicking certain machines while in spectator mode
• Blocks with status lights now stop rendering those lights when obscured by another block
• Improvements to the 3D preview of blueprints
• "Map Location" item and "Zone Planner" block are now available in survival. They don't really do all that much yet.
• Idle quarries no longer are a performance hog
