Compile Button dissapears after first compilation completes

So I’m opening Editor, hitting Compile button, and as soon the compilation finishes (successfully) Compile button dissapears. I’ve tried to regenerate Visual Studio sln file.

The only changes I’ve made since it was working was adding some new Input mappings in Editor and expanding 2 cpp/h files with additional code. I’m using UE4.11-preview-1. This is Vive project.
