Hi Anson
Sorry for the late answer, I was quite busy!
Actually, you should be able to find the new Aic Combinator, just near the standard CC. This one works like the "bad CC" from the previous version. If you don't, this may be because you loaded in an existing version of your game, where CC have already been researched. Unfortunately, there is nothing I can do, as, to unlock the auto increment combinator, I use a standard process from Factorio.
For the tab of virtual signals, you are right. I'll change it in a next version, but not yet, as this is not mandatory. Thanks anyway for the comment!
