Read this before you install it on an existing save.
Factorio ties a mod's saved data to its internal name, so this mod cannot read anything Item Network SA stored. Whatever is banked in your shared network will be lost. Empty it into real chests and tanks before you switch.
Your chests, tanks and everything physically inside them survive, and every chest automatically recovers its item list — see "What carries over" below.

Swap the two mods in one step. Never load your save with Item Network SA removed and nothing replacing it: Factorio will offer to delete every Network Chest, and the items inside them go with it.

What this is

Item Network SA by djmalk has not been updated since June 2025 and still declares Factorio 2.0, so it does not load on 2.1 at all. This is a continuation that ports it and fixes the outstanding crashes. Nothing else.

The mod itself is unchanged in design: Network Chests and Network Tanks are access points to one shared, limitless inventory. Configure a chest to request or provide, and items move instantly — no belts, no bots, no trains. Network Sensors read the network onto the circuit network. Network View is on Ctrl+Shift+N. Quality is fully supported.

Original mod by y_e_a_r (item-network). The Space Age port, the quality system, space platform support and most of the current GUI are djmalk's work. MIT throughout, and this fork keeps every copyright line.

This exists only because the original is stuck on 2.0. If djmalk publishes a 2.1 build, this mod retires and you should go back to his. If he would rather this were not on the portal, it comes down — he has been told that directly.

What is fixed

• Saves that would not load after removing another mod. A chest request whose item no longer exists threw an error inside the per-tick update, every tick, as soon as the surface loaded. Reported twice on the original's page and never answered. Those requests are now dropped, and the game tells you which item it was.
• Wrong-quality items filling your logistic storage. Upgrade requests were asking for normal quality regardless of the target's actual quality, so bots kept rejecting deliveries and the demand never cleared. (Diagnosed and patched on the original's page by Upsidedowneye — thank you.)
• Opening a chest the mod had not registered crashed the game. It now adopts the chest instead.
• The Network View and chest GUI no longer error on items whose mod has been uninstalled.
• The missing LICENSE file is restored, carrying year6b7a's original notice.

What carries over from Item Network SA

The recovery works because the mod writes each chest's requests into that chest's own inventory filters, and filters are stored on the entity rather than in mod data. What the filters cannot tell us is whether a row was a Request or a Provide, so every recovered row comes back as Request with a limit of 0. Getting that wrong is not dangerous — items move between the chest and the network and nothing is destroyed — but check your provide chests after switching.

On first load you will get a chat message saying how many entities were adopted.

Compatibility

Factorio 2.1 only. It cannot be installed on 2.0, and Item Network SA cannot be installed on 2.1 — that is the whole reason this exists. Space Age and Quality are supported but not required.
