So I accidentally deleted a blueprint which an animgraph was relying on, and somehow also deleted the first person cross-hair texture. Afterwards, I re factored and organized my content browser. Now whenever I launch the game this error message appears.

So I tried resolving this issue by adding back the stuff which I deleted, I added the first person character blueprint back, by creating a new project with the FPS template and copying the assets into the main project (somehow the old first person blueprint details appeared … Unreal Magic maybe?) and then I added the first person cross-hair texture.  
Yet I still receive the same warning. Does anyone know a solution to this problem?

The game also crashes when I hit play.
