Initially observed in picture one. For clarity, the block underneath the y=2 repeater is also a dropper.
The intended operation: the hopper under the repeater should be powered first by the weak-powered sandstone, loading the dropper by the crafter with a single block. One redstone tick later, the dust above it activates, which should send an item to the crafter, before powering the dropper behind it, which gives it another item. In the next redstone tick, two half-tick actions occur: in the odd game tick, the dust, torch, and piston are powered off, and in the even game tick, the strong-powered sandstone activates the dropper again, sending another item to the crafter.
The issue: loading a single item into the side and rear droppers should result in them arriving in the crafter in a consistent order (side dropper’s item arrives in the first tick, and the rear in the second). Both items arrive in the proper timing, but the order they arrive is random.
Trying to work my way back, I simplified the component into picture two—where the rear dropper‘s item should be dispensed, while the side hopper’s item gets loaded to be dispensed later. Once again, the item order was randomized.
And in proper bedrock fashion, the simplified component was operating exactly as intended for four hours previous to presently breaking it.
