There is no sanity checking in the save editor that restricts you from doing things in the editor. All of that is purely a visual warning. If you're referring to...

Yep. That's the game itself saving it without the part, not the save editor resetting it. Because it can't save weapons that have incompatible parts like that.

The format the game stores weapons/items in is designed in such a way that it is _impossible_ to define things with incompatible parts that mods such as the randomizer causes....

It's just the way weapon and item data is stored that makes it impossible without modding the game itself.

I have a sample of a save file back when this first became possible. The biggest here is that the sample file was padded to an absurd degree without any...

This is probably either you have an incomplete .NET install, or you possibly have mixed versions of the save editor in the same directory. If you extract the save editor...

Er, what? What file explorer?

Oh you mean the open/save file dialogs. That's most certainly not a bug with the save editor itself.

Did Windows or any other software update in the last few days as well? (Are you on Windows 10?)

Can you check Event Viewer under `Windows Logs`, `Application` for any recent entries about the save editor?
