Config changes not saved

[uscen...@gmail.com]

After upgrading to 2.19 some most of my configs had the Build Environment section reset back to the default for all my projects. After fixing this issue by updating manually all configs once again reset with the next restart. Looking at the config-history files it looks like config changes stopped getting saved with the 2.19 update. Anyone know what could cause this or how to fix it? Trying to find a solution without having to go back to 2.18 if possible.

Thanks.
