error saving objects in *.sav

[Lexx]

See the title. That's *not* the error I am getting with my mod... but it's the error two other people are getting when they try to run my mod and want to save the game.

Anyone knows what exactly is causing this? I've tried it on two different machines, and both are working perfectly fine for me- the other two tester on the other hand simply can't save the game. They are using exactly the same files as I do. Doing some google search, the most I get is "delete the game and reinstall"... but that's not helping at all.

I need some ideas here, folks.

Maybe relate to UAC or file system permissions?

Disabled already + run as admin. Still getting reports that it doesn't help. File paths are all correct as well. Interestingly, using a container item is also crashing the game.

Make sure they have set read only attribute on all files in Data\Proto directory.
