I was working on a Player Piano using logic and wires without the help of ComputerCraft for the challenge. When I reached the point where increasing ram was needed, I reached a limit. Everything else I attempt to add disappears the next time I bring up the world. I am using only Project Red mod with the latest Forge(kept up to date), no optifine or other such enhancers like FoamFix. As you can see in this link, I have an incomplete column, which I am not allowed to complete.
