Alchemistry 1.21.1-2.4.5 RELEASE
Requires ChemLib and AlchemyLib for this version.
Changes:
- Fixed a crash when opening a machine's recipe selector if a modpack recipe's ingredient resolves to no items (custom ingredients and empty tags, the #12 class of crashes).
- Hardened JEI recipe transfers (the "+" button): no more crashes or duplicated items when your inventory only partially matches a recipe, and recipes that resolve to no items no longer shadow real dissolver/liquifier entries in JEI.
- Combiner recipe layouts in JEI and the recipe selector now follow the recipe's chemical-formula order, so some ingredient arrangements may look different; what each recipe crafts and costs is unchanged.
- Reactor energy/input/output ports now connect to adjacent pipes and cables immediately after the multiblock forms, instead of needing the pipe to be broken and replaced.
- Recipe selector choices now stick instead of snapping back to the first matching recipe a tick later, and JEI's "+" transfer respects the exact recipe you clicked.
- Machine tooltips now show the actual configured energy use instead of an unfilled placeholder, and all Alchemistry blocks list the mod name in their tooltip.
- Machine GUIs are no longer double-darkened (via AlchemyLib 1.1.6).
- Recipe selector search now matches item display names.
- Fixed the liquifier's JEI "+" transfer being permanently disabled once the machine had produced any fluid.
- JEI's shift-"+" now fills as many operations as your inventory allows, drawing from your largest stacks.
- Locked machines now accept refills of their recipe's own ingredients (any slot, full stacks); other items are still refused.
- JEI's "+" on a machine locked to a different recipe now refuses cleanly with a "locked" tooltip instead of moving items.
- The recipe selector no longer blurs the machine screen behind it, and ghost-item tooltips now render above neighboring ghost items.
