I can't put productivity modules in any building, including those making intermediate products.

Thanks for your report. I'll take a look once i have some time

I found the issue, it will be fixed in next release

Great

Should be fixed now :)

Yup. Thanks

Ran into this issue again with sapphires in induction hardening facility using prod 2 modules.

diamond and alumina are correctly locked out of productivity, since you could create a perpetual loop for producing alumina or carbon. The diamond recipe was incorrectly producing alumina as byproduct, which is changed for the next version to now produce carbon as byproduct.

I see. I hadn't thought about using prod mods with catalysts that way.
