Productive Frogs

v1.25.3 - 2026-08-09 - Sorting It Out

Fixed

• Iron Furnaces no longer turns one Froglight variant into another. With auto-split switched on, a factory Iron Furnace levelled its input slots by treating every Froglight as the same item, because it compared them by item id and every variant shares one. It then averaged the counts across slots that each kept their own variant, so a furnace holding 64 of one Froglight and 1 of another came out holding 32 and 33. The count never changed, so nothing looked wrong; what changed was which variant you owned, unattended, in your favour or against it. Anything that stores its identity in a data component was affected the same way, not just Froglights. This is Iron Furnaces' bug, reported to them as #229 and still open, so the fix ships here instead: slots are now grouped by variant as well as by item. A furnace holding one variant behaves exactly as it always did. Only active when Iron Furnaces is installed; compat.ironFurnacesAutoSplitFix turns it off. (ironfurnaces_autosplit_fix.md)
• Slimes now appear in the pen with your frogs instead of on top of its wall. A Slime Milk source looked for something solid next to it and put the slime on top of that block. In any pen where a wall, a corner, or a raised rim sits right beside the milk, the solid thing it found was the wall - so every slime landed outside the enclosure, out of reach of the frogs standing in the pool, and free to hop away or fall off the edge. Slimes now appear in an open cell beside the milk, at the pool's own level, and only go above it when there is nowhere else they fit. (#363)
• A source no longer piles its whole output into one square. The spot a source picked was completely fixed, so every slime it ever produced stacked in the same cell. Slimes now spread around the rim of the pool. They also will not be placed hanging over open air any more, so a pool built out over a drop stops feeding slimes to the void. (#363)
