I recently had a problem where the error log showed a compile error for a blueprint and it talked about some variable with a declared class whose type was incorrect. The error log gave me a link to the blueprint, but that blueprint did not have a single reference inside it to that variable or anything with even a similar name. This problem was basically un-fixable from inside the blueprint that the error log was pointing to.
There are many other cases where the error log is showing a problem, and only gives the vaguest of direction in locating the issue.
It would be great if the error log gave more specifics, or even direct links to the problems.
It would be even better if there were a way to right click the error and do something like remove all references for those cases where there simply is no way for a blueprint user to even touch those references.
