I went into the project file, and manually changed some paths. e.g.

c:\users\dnikitin\dev\project\name.cpp

to

c:\users\dnikitin\dev\project\src\name.cpp

Now when I load the project and look into the intellisense diagnostic console, I see complaints that

Can’t open file c:\users\dnikitin\dev\project\name.cpp

Funnily enough, intellisense seems to work after that. Where does it pull those old file paths from, I can’t find them mentioned anywhere in the project directory?
