are you a software designer?
I am, and fixing code issues can be infuriating, especially when more than one programmer is working on a system. Earlier this week I traced a six line error report that was ostensibly on line 1020 of file A to a one line change made on line 126 by another programmer, in a file I wrote that the other programmer was using a function from. Somewhere in his code there was a small error that didn't register until a search function (which is where the error logs said the problem was), my code, and his code (where the error actually existed) all interacted together. It doesn't surprise me at all that in a code base the size of SWTOR there can be multiple problems that all look similar and aren't easy to track.
