python toolbox "no syntax errors" yet non-functional

Question

I make many small changes to the code in my Python Toolbox on a daily basis, and therefore often refresh the toolbox to solidify the changes before running the tool. Usually when I have a syntax error, I am notified when I right-click of the location of the error. However, and I've noticed this a number of times, the message will be "no syntax errors" while the red X remains. In these cases, I am forced to find the part of the code ArcGIS doesn't like. This error does not always translate to a Python syntax error, so compiling to find errors quickly does not work all the time. If a red X is present and my tool is not accessible, the Python Toolbox should be able to notify me where the error is all the time. Has anyone else found this issue?

I apologize, but it turns out this is a repeat of a previous issue:

Again, a syntax error, this time in a dictionary comprehension, foiled my Python Toolbox. Since it was a syntax error in Python, I figured the debugger should be able to inform me of it. Why does it pick up some errors and ignore others?

There are over a thousand lines, plus 6 other .py files that get called with close to 500 lines each, so it's not feasible to publish the whole thing. Plus, it's proprietary =D
I suppose I'd need someone at ESRI to take a look at it.

Could you post your code for the python toolbox?Now having an identical error, yet no GitHub merge conflict text. Even turned on SublimeLinter in SublimeText2 to try and find errors, and came up with nothing. If these are not syntax errors, and are in fact logic errors, why does the .pyt shut down completely and not let me run through the logic of the tool and experience the error myself? Currently, the .pyt has a big red X and tells me "no syntax errors". Any help?
