Belts now need power. All of them. Including all the modded ones. Unmaintained.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
after reloading a save, belts keep moving even after you remove power, they show the no power sign, but the entities still moves

Tested it with unmodified version of your mod, still same results. https://imgur.com/Ponbqim
Sorry idk how to make gifs, but in the images, they still show unpowered signs, but the belts themselves still move
Thanks for letting me know. Should be fixed soon.
