OK, I have found a bug: whenever I turn off the store signal, the output turns off. I don't know why that is, will check it out.
I actually just found out why: the simulation goes step-by-step. When the or gates output goes into the AND gate, the AND gate doesn't know its value and assumes its off. is there a way to fix this?
i fixed it: overwriting the multiplexer into its own chip fixes it
