The description for the 8bit D flip flop is completely wrong. The text, the diagram, the logic table, all talk about different pins that don't match to each other.

Steam topic for reference : https://steamcommunity.com/app/2198800/discussions/0/3721691844082395857/ There's a bug when loading a value in the counter : it looks like it doesn't affect the internal value. When we start counting again after loading the new value, it keeps counting from the value it had BEFORE we load the new one.
