Deliver nuclear fuel to reactors via the logistics network. Update of alleledev's Logistics Reactor Next, originally based on illysune's Logistics Reactor.
Mods introducing new content into the game.
If you get a runtime error, please include either the save file and/or very explicit list of directions that led to the error (i.e. error when placing a reactor after having loaded a pre-existing save and updated other mods, error when placing a reactor after adding the mod to a pre-existing save, error when removing reactor in a unique way, etc)
If you cannot recreate the error, save file and/or mod list may help to determine the cause. The more detail you can provide, the easier it will be to figure out the cause, and the less time it will take to figure out a solution.
