The "BUS" component is unusably bugged. When multiple are used in a chip, one or more start randomly flickering and giving out signals, despite having no input. This issue doesn't happen if I replace them with normal cables, so it is obviously the buses themselves.
Also, more rarely but still sometimes, buses that have an input start flickering, when they should be stably on.
I have checked, all my buses have only one input.
There should be a more obvious input method too, like an attachment node at the end or similar.
