Found this file in my override. What is it?

$RMF33KN.ITM

It seems to be a scroll of "Summon Cow", not sure which mods added it.

Thank you. I don't recognize the suffix either.

So, question: I first had this file in my override and played with it in my current savegame.

Then I removed it and reloaded the game and played without it.

Now I wish to add it back to my override folder.

Will my savegame be nuked due to this ? Or override overwriting is "safe"?

Moving things in and out of the override can't completely break a save in the way other mods do. At worst, you might run into a missing resource situation. For example, if your save had a character with that item and you removed it from your override, that inventory slot would become an undroppable "invalid item".

Some resources become embedded in saves once they come up; if you removed an ARE from your override after visiting the area, that save wouldn't even notice the change.

You possibly could do a change-log to know which mod added it.
