Hi ..

I made a combinator where I have an rpg going into a splitter, and then the signal being routed to 3 subtractors. I saved the combinator. When I recall it, the routing is different, however. Yikes! ????

I figured it out, but I'm still confused (ha). I apparently needed to created a line mixer. Now it works.

But, I didn't have a mixer created before, so why are the two instances different?
