Every time I open up the dev branch (separate install) it resets the currently set profile. I tried with completely new profile files, I deleted all the stuff in the appdata, nothing helped. One thing I didn't try is to mess with the registry.
So basically I launch the dev build and I always get that welcome screen with default settings.
Let me know what information/files can I provide to help identifying the issue and/or if someone has a solution to the problem. {F27871}
