Particle Desktop IDE - Compile before save problem

[versamodule]

I have been using Particle Desktop IDE excursive for over a year now. After making changes to a file, I just click Compile, as I know it will save it first save all changed files, and then compile. It always has done so.
But for a while now I noticed that it’s not doing this anymore. If i make a change to any file and click Compile it shows that it saved the file (by removing the blue dot on the file’s tab) and it does compile it. Yet when I flash it those changes are not applied to the running code. If i make changes and save first, then click build, and flash they do. I have tried this several times and its repeatable.
