what does downgrade mean when loading a game with new mods

[Delaborga]

are they still active, or? i dont want to delete , or remove anything, if it aint breaking my save file i might as well have it be there but does it still apply and work ingame if it says downgrade or remove?

This is rather complex....

Game code is comparable to building a house by creating then dropping pieces into place using GPS coordinates. Everything still has to function, and not conflict yet the work putting them in place is done indirectly instead of directly. Mods get their name because they modify existing game files keeping with the analogy a mod would be like telling the game the bed which was formerly a twin is now a king, the sheets are now a different material, of the bed frame is now different. However those modifications require the bed to be found as expected for the mod to work, and the change not conflict with anything else. This means mods are designed for the base code to be the same as when they where last updated. The more expansive the mod the more likely any update will alter what the mod is trying to modify which breaks the mod. The two ways around this is waiting for the mods to update, or downgrading the game back to a version the mods worked with.
