I am not sure how to consistently recreate this issue, but it has been a major headache for me for quite some time. I am writing tests using the Cucumber framework - that is, feature files with step definition files underneath. I very frequently run into this “Save Problems” popup when I adjust my stepdef file, often occurring if I make a lot of small changes in multiple spots. I should also note that I have had the autocomplete (I’m not sure what that function is called) bug out and throw an exception on multiple occasions, and I believe it may be related to this issue. I always know I am going to see this popup when I make a change to the code and it doesn’t light up correctly (a global variable not showing blue or parts of a comment retaining their uncommented color, etc. When I then go to run one of my test case or feature files I am met with this error, and upon closing and reopening my stepdef file I usually find my most recent changes gone.
I have seen others post about this issue, but I am doubtful anyone has experienced it with as much frequency as I have…
