Create Crafts & Additions (https://github.com/mrh0/createaddition/tree/main) provides native ComputerCraft support for a couple of the blocks it adds (https://github.com/mrh0/createaddition/blob/main/COMPUTERCRAFT.md). The issue is that when you also have UnlimitedPeripheralWorks installed it overwrites the CC&A native APIs resulting in the electric motor no longer having a "setSpeed" function for example and instead having "getConfiguration", "getScrollValue", "setScrollValue", etc. This seems to persist even when disabling the Create integration in config.
