This wasn't a problem at all, and for the last few weeks, it started to happen. Basically any change to the file is outdating the comment even if the line didn't change the position and the line didn't change the content.
This started to annoy a lot recently all our team.
I understand that you have to solve the "High Plains Drifter" problem, but comments started to be outdated even for lines of code that did not change their position and the line itself didn't change at all.
