My combinators don't update with this mod installed. Let me know if I can help troubleshoot.

This mod allows you to pause and unpause some or all of the combinators in the world. So you can single-tick update them, or just keep them paused for inspection purposes.

You should be able to see all this stuff in the UI, but it's also possible to do it all with keyboard shortcuts. Can you make sure you haven't activated it?

Okay. I installed it but I hadn't (intentionally) done anything with it yet. I'll take another look in the settings and make sure I didn't accidentally activate something.
