This mod completely disables the Logistic System Research, as I believe it makes belts largely obsolete and allows "brute forcing" bot solutions to complex logistics problems. Belt Spaghetti is a serious problem that is difficult to resolve, and bots provide a convenient bandaid to avoid the problem entirely, which I feel takes away a lot of the enjoyment of factory management.

This mod aims to prevent using bots to completely replace belts, without affecting the unique automation improvement bots provide. As a result, The initial Logistics Research is still available, so Roboports, Construction Bots and Logistics Bots are still available, as are Passive Provider Chests and Storage Chests, allowing bots to still resupply the player and perform building and repair tasks.

Version 1.03 allows Logistics on vehicles (the tank and the car) without needing the disabled research. As a consequence, inserters can no longer remove items from cars or tanks, to prevent them from becoming "DIY requestor chests". Vehicle logistics can be disabled in the Startup settings.

This mod can be added and removed on existing savegames. In this case, the research will be hidden from the research screen, and all advanced chests will no longer be craftable or usable as recipes. Existing chests won't be affected, and any assemblers previously set up to create the advanced logistics chests will continue to function normally.

The mod icon is adapted from the in-game Logistics research icon, available from the Factorio Wiki, and also uses the Wikimedia Commons "No" symbol, which is available under the public domain.
