I have an issue with installed fonts suddenly showing as not available or uninstalled in InDesign CC. The font is installed, and working properly in the document. The next time I open the document, the fonts show pink and unavailable. The only way I've been able to resolve it is to reinstall the fonts, even though Windows tells me the font is already installed. I can see the fonts on other programs without an issue. It seems to be random, so it's not any particular font consistently. These are not Typekit fonts. Any ideas on how to get InDesign to stop "losing" my fonts?
