A tooltip is missing when you see these blue lines of code:

These are a bit hard to test because it's hard to differentiate if a tooltip is part of the base game localization or it was added by a mod. So, whether you see one of these or not depends on your mod list. If you find any, either copy the blue line here, or send a screenshot and I'll include it in the localization. Thanks!
