Project created with source engine 4.5.0 missing StandardMacros Library

I created a new project with source engine 4.5.0. In this new project, I couldn’t use the macros like loop, isvalid and such, which belongs to the standard library. I checked that the standard library is in the engine folder Engine|Content|EditorBlueprintResources|.

Why can’t my blueprint find it; Is it a bug of the source code engine like it doesn’t set up the reference to this lib correctly?

Strange. In my case they’re here.
No special procedures performed.

Well that’s weird, I will compile the engine again to see what happens.

Thanks for helping me confirm this. And it turns out it’s because the change I made related to Ikinema(a plugin I use). I will mark this question as solved.
