Visual Studio 2013 Rebuild problem

Question

I have a asp.net solution which consists of multiple class library whose dll' are been used in one web application.When I build and rebuild the class library I don't face any issue, later when I try to build and rebuild the solution few of my dll files gets deleted from bin.Tried adding reference path but in vein.

Warning : Could not resolve this reference. Could not locate the assembly "classlibrary2". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. classlibrary1

Error 10 The type or namespace name 'Classlibrary1' could not be found (are you missing a using directive or an assembly reference?)

Note:All projects are in same framework

how does it help?it just output path of class library.In case, if I avoid then there will a be problem in deploying the solution, as I only deploy the main solution.

Could you please try avoiding the first step and only add the dll by reference to the solution?
