For some reason that I can't quite figure out, the Crushers from Crushing Industry seem to be incompatible with Rigor Modules. If you set a recipe (such as Coal Crushing) and then insert a rigor module, it un-sets the recipe and prevents you from selecting another recipe - nothing happens when you click a recipe in the selection menu. You also can't manually remove the module anymore, since the menu to do so isn't visible until a recipe is selected, so you basically just have to pick up the machine.

Thanks for reporting this! It's an interesting bug. I'll take a look.

Can you share what other mods are enabled? I can't reproduce this with just rigor module and crushing industry.

Unfortunately it's a pretty heavy modlist, so that will make it awkward to narrow things down... I have it posted here.

Looking at things in-game, the tooltip that shows what mods are impacting a given entity display the following:

Electric Crusher is modified by Crushing Industries Tweaks and Mod Compat and Any Planet Start (if it happens to be relevant, I'm currently doing Vulcanus start)

The Crushing recipes themselves are just Crushing Inudstry -> Crushing Industries Tweaks and Mod Compat -> Rigor Module.

So it seems likely it may be related to the Tweaks mod?

I don't know if it's pertinent, but I did try to see if I could forcibly set the recipe by using a circuit signal and the Set Recipe checkmark in the machine, but unfortunately I can't find a Signal for the Crushing Industry recipes. If Rigor somehow relies on recipe signals then maybe that could be relevant.

Tracking issue here

Fixed with version 0.4.4.
