Changed

• IC2 copper ore/ingot are intentionally not included in the current progression; vanilla copper is used instead.
• Generator fuel handling now uses vanilla burn times, so normal burnable items produce EU.
• Storage GUI sync now handles large EU values without signed short overflow.
• Reactor output is generated continuously into an internal EU buffer instead of dumping in short burst spikes.
• Cable items and block models were adjusted to better match old IC2 cable visuals.
• Machine processing is data-driven through ic2reborn:machine_processing recipes.
• Mod description now avoids pinning the reboot to one specific old IC2 version.

Fixed

• Machine GUIs now sync energy and progress more reliably.
• Storage blocks no longer display negative EU values above vanilla signed-short limits.
• Generator GUI slot alignment was adjusted.
• Oversized GUI clipping was reduced for larger screens such as the reactor.
• Machine active sound loops now stop when the machine stops.
• Machine active animation no longer flickers between fuel items in the Generator.
• Reactor can connect to cables.
• Cables no longer break when placed in water.
• Rubber Sapling can be placed and grows like a normal sapling.
• Rubber Leaves now render and behave more like leaves.
• Reinforced Door is treated as a door item/block pair instead of a normal cube block item.
• Nightvision Goggles texture was restored.
• Silver Ore texture and material loop were added.
• Treetap and Cell interactions validate server permissions.
• Rubber Trampoline and Iron Fence movement behavior is server-authoritative for multiplayer.

Known Limitations

• This is not full IC2 parity.
• Cable loss, voltage packets, shock damage, cable burn rules, detector cable behavior, and splitter cable behavior are not fully implemented yet.
• Transformers are simplified tiered buffers, not full directional IC2 transformers.
• Electric item charging and discharging is not implemented yet.
• Batteries, crystals, electric tools, armor, upgrades, and storage charge slots are mostly not functional yet.
• Canner and Electrolyzer use simplified behavior.
• Induction Furnace does not have the old heat mechanic yet.
• Miner, Teleporter, Terraformer, Tesla Coil, Cropmatron, Personal Safe, Trade-O-Mat, Energy-O-Mat, and many utility blocks are not release-quality gameplay systems yet.
• Reactor behavior is playable but simplified and not exact old IC2 simulation parity.
• Balance values and some visuals are still first-pass alpha values.
