It seems like the blueprints feature broke crow on some (at least mine) windows machines.
On my linux instance, executing
pop_backon an empty vector doesn't seem to do anything. On my windows instance though, it crashes the program. This PR just checks if theblueprints-vector is empty and only if it isn't, removes an item.It is undefined behavior to use
pop_backon an empty vector and should be avoided.
