Sky Frogs

Iron Furnaces stops eating your Froglights, in both of the ways it was doing it.

Fixed

• Iron Furnaces takes your Froglights again. Some players found that no Froglight would go into an Iron Furnace at all, by hand or by pipe, while a vanilla furnace took them fine, and that restarting the game fixed it until it came back. Iron Furnaces remembers whether an item can be smelted in a list keyed by the item, and every Froglight variant is the same item, so the first Froglight a furnace ever saw decided the answer for all of them until the game closed. A Froglight with no variant on it, the kind a Copy-Paste Gadget makes, has nothing to smelt into, and one of those was enough to lock out every other Froglight for the rest of the session. Froglights are now asked about one at a time. Reported on CurseForge by user_qqgd4audept0i3qy, Larronos and user_w647p447peuez0hl, and on Discord by more people than we can list.
• Iron Furnaces no longer turns one Froglight variant into another. If you ran Froglights through a factory Iron Furnace with auto-split switched on, the furnace treated every Froglight as the same item and levelled the counts across its input slots. Each slot kept its own variant, so a furnace holding 64 of one Froglight and 1 of another came out holding 32 and 33. Your total never changed, which is why nothing ever looked wrong; what changed was which variant you owned. It has been in the pack since v1.4.3, and it ran on its own, in either direction - you could lose a stack of Nether Star Froglights or mint one. Anything storing its identity the way a Froglight does was affected the same way. This is Iron Furnaces' bug, reported to them and still open, so the fix ships in Productive Frogs instead: slots are now matched on variant as well as item. A furnace holding one variant behaves exactly as it always did. Thanks to abyssquidd (#225) and millllehzh (#220) for the reports.
• Slimes appear in the pen with your frogs instead of on top of its wall. A Slime Milk source looked for something solid beside it and put the slime there, so in any pen with a wall or a raised rim next to the milk, slimes landed outside the enclosure, out of reach of the frogs, and could hop away.
• A milk source spreads its slimes around the pool instead of stacking every one of them in the same square, and will not drop them over open air, so a pool built out over a ledge stops feeding slimes to the void.

Changed

• Productive Frogs 1.25.2 -> 1.25.3 ("Sorting It Out"), which carries all three fixes above.
• Nine other mods brought up to current: FTB Quests, Skyblock Builder, Moonlight Lib, JEI, Jade, SuperMartijn642's Core Lib, and the Sophisticated Core / Backpacks / Storage set. Sodium stays on 0.8.12; its newer build is a beta, and the renderer is not something to ship untested.
