yor 0.60 bug

This is due to an error in the ImprovementDefs.xml file, specifically the upgrades from tag. It is set to upgrade from itself. If you search the file for "industrialcollective" then scroll down a little bit you should see this

<!-- Prerequisites -->
 
    <Prerequ>
      <Techs>
        <Option>IndustrialMechanizationTech</Option>
      </Techs>
      <UpgradesFrom>IndustrialCollective</UpgradesFrom>
    </Prerequ>

You need to change <UpgradesFrom>IndustrialCollective</UpgradesFrom> to

<UpgradesFrom>ManufacturingCollective</UpgradesFrom>

Note that it will only take effect on newly created games after the edit.

I've forwarded this to the designer (bonus points for supplying the fix too!). Thanks for the post.

Thanks for the report, fixed internally, will be in next patch.
