Most of that info is already posted at the top of the post, as seen here:
Version number 1.0.1.5325
Branch Main
Modded/unmodded Yes, but I removed mods.
No screenshot because all I would have is the screenshot showing the current reduced values since I didn't expect the game to reset the values, hence no screenshot of the before.
In addition, giving specific numerical values should be enough for the dev team to see that there is possibly an issue and work to recreate it, which should be pretty easy for them since all they have to do is craft a weapon that gets fine, masterwork, or legendary stat boosts, save and reload, and see if those stat boosts reset.
If they can replicate it simply, that confirms it's most likely wide-spread.
