This sounds like the snapshot of files the code model is aware of got 
heavily reduced. We have fixed an issue like that recently (opening a 
project made creator forget about previously opened projects). But since 
it is still valid for you, it might be another issue.

Does the issue also occur for other projects, e.g. qmake projects?

Here [1] is a patch that adds some qDebugs() in order to track the 
snapshot size. It would be interesting to know at which point the 
reported size drops permanently.
