Well, the game technically supports it

Here, the first loop will successfully increase the concentration by 3 over 2 turns. Attaching the second loop creates a problem.

Obviously this arises because the game uses pathfinding based on the directionality of the attached machinery and doesn’t know which direction the attached belts are. Still, this is useful to do things like make a +7 concentrator from 3 evaporators, but linking other things to the chain gets messy because the game can’t resolve the path direction.

*Hmm, I wonder if I can make gate logic… these ARE basically state machines (graph theory and all)

Directional Belts (announced in last week’s vlog) should allow you to do just this.
