Well… as I understand the history, the EnhancedInput plugin was introduced in very late 4.x, turned on my default in 5.0 and is on it’s way (at this point) to being part of the standard. It could be this halfway integration that’s the problem, but I don’t know that.
Some of what I’ve read on the possible issue (from people having similar but not the same problems — or at least problems solvable by means that are not solving my problem — are that starting with the Blank project is required to trigger the problem. Others have had the EnhancedInput tag in their Private array rather than public. Heck I even tried having it in both.
I’m kinda hoping that someone who knows how this build process works can weigh in with a solution. If including those includes works for you, if you didn’t start with the blank project template, I have good reason to believe that you’re not experiencing the bug.
