It happened again. Project just started showing those same compilation errors. Add again, the solution was the same.
The error appeared after I modified the precompiled header to include <vector> in it. First time it happened it was also around the time I modified precompiled header to include <memory>. So now I am wondering if the problem has something to do with editing the precompiled header.
Thought I did modify it once to add <cassert> and didn’t get there errors.
